General DescriptionThe MAX3440E–MAX3444E fault-protected RS-485 and J1708 transceivers feature ±60V protection from signal faults on communication bus lines. Each device contains one differential line driver with three-state output and one differential line receiver with three-state input. The 1/4-unit-load receiver input impedance allows up to 128 trans-ceivers on a single bus. The devices operate from a 5V supply at data rates of up to 10Mbps. True fail-safe inputs guarantee a logic-high receiver output when the receiver inputs are open, shorted, or connected to an idle data line.Hot-swap circuitry eliminates false transitions on the data bus during circuit initialization or connection to a live backplane. Short-circuit current-limiting and ther-mal shutdown circuitry protect the driver against exces-sive power dissipation, and on-chip ±15kV ESD protection eliminates costly external protection devices.The MAX3440E–MAX3444E are available in 8-pin SO and PDIP packages and are specified over industrial and automotive temperature ranges.ApplicationsRS-422/RS-485 Communications Truck and Trailer Applications Industrial NetworksTelecommunications Systems Automotive Applications Features♦±15kV ESD Protection ♦±60V Fault Protection♦Guaranteed 10Mbps Data Rate (MAX3441E/MAX3443E)♦Hot Swappable for Telecom Applications ♦True Fail-Safe Receiver Inputs♦Enhanced Slew-Rate-Limiting Facilitates Error-Free Data Transmission(MAX3440E/MAX3442E/MAX3444E)♦Allow Up to 128 Transceivers on the Bus ♦-7V to +12V Common-Mode Input Range♦Automotive Temperature Range (-40°C to +125°C)♦Industry-Standard PinoutMAX3440E–MAX3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers________________________________________________________________Maxim Integrated Products 1Pin Configurations and Typical Operating CircuitsOrdering Information19-2666; Rev 1; 12/05For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642,or visit Maxim’s website at .Ordering Information continued at end of data sheet.M A X 3440E –M A X 3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

MAX3440E/MAX3441E (RS-485/RS-422)Detailed DescriptionThe MAX3440E–MAX3444E fault-protected transceivers for RS-485/RS-422 and J1708 communication contain one driver and one receiver. These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled (see the True Fail-Safe section). All devices have a hot-swap input structure that prevents disturbances on the differential signal lines when a circuit board is plugged into a hot back-plane (see the Hot-Swap Capability section). The MAX3440E/MAX3442E/MAX3444E feature a reduced slew-rate driver that minimizes EMI and reduces reflec-tions caused by improperly terminated cables, allowing error-free data transmission up to 250kbps (see the Reduced EMI and Reflections section). The MAX3441E/MAX3443E drivers are not slew-rate limited, allowing transmit speeds up to 10Mbps.DriverThe driver accepts a single-ended, logic-level input (DI) and transfers it to a differential, RS-485/RS-422level output (A and B). Deasserting the driver enable places the driver outputs (A and B) into a high-imped-ance state.ReceiverThe receiver accepts a differential, RS-485/RS-422level input (A and B), and transfers it to a single-ended,logic-level output (RO). Deasserting the receiver enable places the receiver inputs (A and B) into a high-imped-ance state (see Tables 1–7).Low-Power Shutdown(MAX3442E/MAX3443E/MAX3444E)The MAX3442E/MAX3443E/MAX3444E offer a low-power shutdown mode. Force DE low and RE high to shut down the MAX3442E/MAX3443E. Force DE and RE high to shut down the MAX3444E. A time delay of 50ns prevents the device from accidentally entering shutdown due to logic skews when switching between transmit and receive modes. Holding DE low and RE high for at least 800ns guarantees that the MAX3442E/MAX3443E enter shutdown. In shutdown, the devices consume a maxi-mum 20µA supply current.±60V Fault ProtectionThe driver outputs/receiver inputs of RS-485 devices in industrial network applications often experience voltage faults resulting from shorts to the power grid that exceed the -7V to +12V range specified in the EIA/TIA-485 standard. In these applications, ordinary RS-485devices (typical absolute maximum -8V to +12.5V)require costly external protection devices. To reduce system complexity and eliminate this need for external protection, the driver outputs/receiver inputs of the MAX3440E–MAX3444E withstand voltage faults up to ±60V with respect to ground without damage.Protection is guaranteed regardless whether the device is active, shut down, or without power.True Fail-SafeThe MAX3440E–MAX3444E use a -50mV to -200mV differential input threshold to ensure true fail-safe receiver inputs. This threshold guarantees the receiver outputs a logic high for shorted, open, or idle data lines. The -50mV to -200mV threshold complies with the ±200mV threshold EIA/TIA-485 standard.M A X 3440E –M A X 3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers 12______________________________________________________________________________________±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against ESD encountered during handling and assembly. The MAX3440E–MAX3444E receiver inputs/driver outputs (A, B) have extra protection against static electricity found in normal operation. Maxim’s engineers have developed state-of-the-art structures to protect these pins against ±15kV ESD without damage. After an ESD event, the MAX3440E–MAX3444E continue working without latchup.ESD protection can be tested in several ways. The receiver inputs are characterized for protection to ±15kV using the Human Body Model.ESD Test ConditionsESD performance depends on a number of conditions.Contact Maxim for a reliability report that documents test setup, methodology, and results.Human Body ModelFigure 9a shows the Human Body Model, and Figure 9b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of inter-est, which is then discharged into the device through a 1.5k Ωresistor.Driver Output ProtectionTwo mechanisms prevent excessive output current and power dissipation caused by faults or bus contention.The first, a foldback current limit on the driver output stage, provides immediate protection against short cir-cuits over the whole common-mode voltage range. The second, a thermal shutdown circuit, forces the driver out-puts into a high-impedance state if the die temperature exceeds +160°C. Normal operation resumes when the die temperature cools to +140°C, resulting in a pulsed output during continuous short-circuit conditions.MAX3440E–MAX3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers______________________________________________________________________________________13Figure 9a. Human Body ESD Test ModelM A X 3440E –M A X 3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers 14______________________________________________________________________________________Hot-Swap CapabilityHot-Swap InputsInserting circuit boards into a hot, or powered, back-plane may cause voltage transients on DE, DE/RE, RE ,and receiver inputs A and B that can lead to data errors.For example, upon initial circuit board insertion, the processor undergoes a power-up sequence. During this period, the high-impedance state of the output drivers makes them unable to drive the MAX3440E–MAX3444E enable inputs to a defined logic level. Meanwhile, leak-age currents of up to 10µA from the high-impedance out-put, or capacitively coupled noise from V CC or G ND,could cause an input to drift to an incorrect logic state.To prevent such a condition from occurring, the MAX3440E–MAX3443E feature hot-swap input circuitry on DE, DE/RE, and RE to guard against unwanted dri-ver activation during hot-swap situations. The MAX3444E has hot-swap input circuitry only on RE .When V CC rises, an internal pulldown (or pullup for RE )circuit holds DE low for at least 10µs, and until the cur-rent into DE exceeds 200µA. After the initial power-up sequence, the pulldown circuit becomes transparent,resetting the hot-swap tolerable input.Hot-Swap Input CircuitryAt the driver-enable input (DE), there are two NMOS devices, M1 and M2 (Figure 10). When V CC ramps from zero, an internal 15µs timer turns on M2 and sets the SR latch, which also turns on M1. Transistors M2, a 2mA current sink, and M1, a 100µA current sink, pull DE to GND through a 5.6k Ωresistor. M2 pulls DE to the disabled state against an external parasitic capaci-tance up to 100pF that may drive DE high. After 15µs,the timer deactivates M2 while M1 remains on, holding DE low against three-state leakage currents that may drive DE high. M1 remains on until an external current source overcomes the required input current. At this time, the SR latch resets M1 and turns off. When M1turns off, DE reverts to a standard, high-impedance CMOS input. Whenever V CC drops below 1V, the input is reset.A complementary circuit for RE uses two PMOS devices to pull RE to V CC .__________Applications Information128 Transceivers on the BusThe MAX3440E–MAX3444E transceivers 1/4-unit-load receiver input impedance (48k Ω) allows up to 128transceivers connected in parallel on one communica-tion line. Connect any combination of these devices,and/or other RS-485 devices, for a maximum of 32-unit loads to the line.Reduced EMI and ReflectionsThe MAX3440E/MAX3442E/MAX3444E are slew-rate limited, minimizing EMI and reducing reflections caused by improperly terminated cables. Figure 11shows the driver output waveform and its Fourier analy-sis of a 125kHz signal transmitted by a MAX3443E.High-frequency harmonic components with large ampli-tudes are evident.Figure 12 shows the same signal displayed for a MAX3442E transmitting under the same conditions.Figure 12’s high-frequency harmonic components are much lower in amplitude, compared with Figure 11’s,and the potential for EMI is significantly reduced.Figure 10. Simplified Structure of the Driver Enable Pin (DE)In general, a transmitter’s rise time relates directly to the length of an unterminated stub, which can be dri-ven with only minor waveform reflections. The following equation expresses this relationship conservatively:Length = t RISE / (10 x 1.5ns/ft)where t RISE is the transmitter’s rise time.For example, the MAX3442E’s rise time is typically 800ns, which results in excellent waveforms with a stub length up to 53ft. A system can work well with longer unterminated stubs, even with severe reflections, if the waveform settles out before the UART samples them.RS-485 ApplicationsThe MAX3440E–MAX3443E transceivers provide bidi-rectional data communications on multipoint bus trans-mission lines. Figures 13 and 14show a typical network applications circuit. The RS-485 standard covers line lengths up to 4000ft. To minimize reflections and reduce data errors, terminate the signal line at both ends in its characteristic impedance, and keep stub lengths off the main line as short as possible.J1708 ApplicationsThe MAX3444E is designed for J1708 applications. To configure the MAX3444E, connect DE and RE to G ND.Connect the signal to be transmitted to TXD. Terminate the bus with the load circuit as shown in Figure 15. The drivers used by SAE J1708 are used in a dominant-mode application. DE is active low; a high input on DE places the outputs in high impedance. When the driver is disabled (TXD high or DE high), the bus is pulled high by external bias resistors R1 and R2. Therefore, a logic level high is encoded as recessive. When all transceivers are idle in this configuration, all receivers output logic high because of the pullup resistor on A and pulldown resistor on B. R1 and R2 provide the bias for the recessive state.C1 and C2 combine to form a 6MHz lowpass filter, effec-tive for reducing FM interference. R2, C1, R4, and C2combine to form a 1.6MHz lowpass filter, effective for reducing AM interference. Because the bus is untermi-nated, at high frequencies, R3 and R4 perform a pseudotermination. This makes the implementation more flexible, as no specific termination nodes are required at the ends of the bus.MAX3440E–MAX3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers______________________________________________________________________________________155.00MHz 500kHz/div 020dB/div Figure 11.

IN/OUT OFF-ISOLATIONON PHASE__________Applications InformationPower-Supply ConsiderationsOverviewThe MAX4051/MAX4052/MAX4053 and MAX4051A/MAX4052A/MAX4053A construction is typical of most CMOS analog switches. They have three supply pins:V+, V-,and GND. V+ and V- are used to drive the inter-nal CMOS switches and set the limits of the analog volt-age on any switch. Reverse ESD-protection diodes are internally connected between each analog signal pin and both V+ and V-. If any analog signal exceeds V+ or V-, one of these diodes will conduct. During normal operation, these (and other) reverse-biased ESD diodes leak, forming the only current drawn from V+ or V-.Virtually all the analog leakage current comes from the ESD diodes. Although the ESD diodes on a given signal pin are identical, and therefore fairly well balanced,they are reverse biased differently. Each is biased by either V+ or V- and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V+ and V- pins consti-tutes the analog signal path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage cur-rents of either the same or opposite polarity.There is no connection between the analog signal paths and GND.MAX4051/A, MAX4052/A, MAX4053/ALow-Voltage, CMOS AnalogMultiplexers/Switches________________________________________________________________ ______________________11Table 1. Truth Table/Switch ProgrammingX = Don’t care * ADDC not present on MAX4052.Note:NO and COM pins are identical and interchangeable. Either may be considered an input or output; signals pass equally wellin either direction.M A X 4051/A , M A X 4052/A , M A X 4053/AV+ and G ND power the internal logic and logic-level translators, and set both the input and output logic lim-its. The logic-level translators convert the logic levels into switched V+ and V- signals to drive the gates of the analog signals. This drive signal is the only connec-tion between the logic supplies (and signals) and the analog supplies. V+ and V- have ESD-protection diodes to GND.The logic-level thresholds are TTL/CMOS compatible when V+ is +5V. As V+ rises, the threshold increases slightly, so when V+ reaches +12V, the threshold is about 3.1V; above the TTL-guaranteed high-level mini-mum of 2.8V, but still compatible with CMOS outputs.Bipolar SuppliesThe se devices operate with bipolar supplies between ±3.0V and ±8V. The V+ and V- supplies need not be symmetrical, buttheir sum cannot exceed the absolute maximum rating of +17V.Single SupplyThese devices operate from a single supply between +3V and +16V when V- is connected to GND. All of the bipolar precautions must be observed. At room temper-ature, they actually “work” with a single supply at near or below +1.7V, although as supply voltage decreases,switch on-resistance and switching times become very high.Overvoltage ProtectionProper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi-mum ratings, because stresses beyond the listed rat-ings can cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by the logic inputs (NO) and by COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with the supply pins for overvoltage protection (Figure 1).Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V-should not exceed 17V. These protection diodes are not recommended when using a single supply if signal levels must extend to ground.High-Frequency PerformanceIn 50?systems, signal response is reasonably flat up to 50MHz (see Typical Operating Characteristics ).Above 20MHz, the on response has several minor peaks which are highly layout dependent. The problem is not turning the switch on, but turning it off. The off-state switch acts like a capacitor, and passes higherfrequencies with less attenuation. At 10MHz, off isola-tion is about -45dB in 50?systems, becoming worse (approximately 20dB per decade) as frequency increases. Higher circuit impedances also make off iso-lation worse. Adjacent channel attenuation is about 3dB above that of a bare IC socket, and is entirely due to capacitive coupling.Low-Voltage, CMOS Analog Multiplexers/Switches 12__________________________________________________________________ ____________________Figure 1.

General Description
The MAX3222E/MAX3232E/MAX3237E/MAX3241E/ MAX3246E +3.0V-powered EIA/TIA-232 and V.28/V.24 communications interface devices feature low power consumption, high data-rate capabilities, and enhanced electrostatic-discharge (ESD) protection. The enhanced ESD structure protects all transmitter outputs and receiver inputs to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge (±9kV for MAX3246E), and ±15kV using the Human Body Model. The logic and receiver I/O pins of the MAX3237E are protected to the above standards, while the transmitter output pins are protected to ±15kV using the Human Body Model.

+5V/+3V, 12-Bit, Serial, Force/Sense DACs with 10ppm/°C Internal Reference
General Description
The MAX5122/MAX5123 low-power, 12-bit, voltage-output, digital-to-analog converters (DACs) feature an internal precision bandgap reference and output amplifier. The MAX5122 operates on a single +5V supply with an internal +2.5V reference, and offers a configurable output amplifier. If necessary, the user can override the on-chip, <10ppm/°C voltage reference with an external reference. The MAX5123 has the same features as the MAX5122 but operates from a single +3V supply and has an internal +1.25V precision reference. The user-accessible inverting input and output of the amplifier allows specific gain configurations, remote sensing, and high output drive capability for a wide range of force/sense applications. Both devices draw only 500µA of supply current, which reduces to 3µA in power-down mode. In addition, their power-up reset feature allows for a user-selectable initial output state of either 0V or midscale and reduces output glitches during power-up. The serial interface is compatible with SPI™, QSPI™, and MICROWIRE™, which makes the MAX5122/MAX5123 suitable for cascading multiple devices. Each DAC has a double-buffered input organized as an input register followed by a DAC register. A 16-bit shift register loads data into the input register. The DAC register may be updated independently or simultaneously with the input register. Both devices are available in a 16-pin QSOP package and are specified for the extended-industrial (-40°C to +85°C) operating temperature range. For pin-compatible 14-bit upgrades, see the MAX5171/MAX5173 data sheet; for the pin-compatible 13-bit version, see the MAX5132/ MAX5133 data sheet. ♦ Single-Supply Operation +5V (MAX5122) +3V (MAX5123) ♦ Built-In 10ppm/°C max Precision Bandgap Reference +2.5V (MAX5122) +1.25V (MAX5123) ♦ SPI/QSPI/MICROWIRE-Compatible, 3-Wire Serial Interface ♦ Pin-Programmable Shutdown Mode and PowerUp Reset (0 or Midscale Output Voltage) ♦ Buffered Output Capable of Driving 5kΩ 100pF or 4–20mA Loads ♦ Space-Saving 16-Pin QSOP Package ♦ Pin-Compatible 13-Bit Upgrades Available (MAX5132/MAX5133) ♦ Pin-Compatible 14-Bit Upgrades Available (MAX5171/MAX5173)
