当有电话呼入时，电话线上传输的25HZ、90V 的交流振铃信号由C1、C2隔离直流后由整流桥整流，整流后的直流电压值较高，经光电隔离器U1后输出TTL脉冲信号，该脉冲经74LS123整形成大方波信号，该方波信号送至单片机的P3.5引脚进行计数，当计数值达到预设值时，单片机P1.0引脚输出高电平，三极管Q1导通则继电器K1动作，将负载电阻R5（330Ω）接入电路实现模拟摘机。

这里所说的模拟摘机是指将R5接入电路后，电话线上就会出现大于10mA的电流，交换中心检测到这一电流后就不再输出振铃信号而是转为接通电话。

人们手动摘机接通电话时的工作过程与此一致，因此称为模拟摘机。

如果振铃信号没有达到预设值就消失，则单片机的计数值清零，控制器不动作。

HD74AC165/HD74ACT165Parallel-Load 8-bit Shift RegisterADE-205-374 (Z)1st. EditionSep. 2000 DescriptionThis 8-bit serial shift register shifts data from QA to QHwhen clocked, Parallel inputs to each stage areenabled by a low level at the Shift/Load Input. Also included is a gated clock input and a complementary output from the eighth bit.Clocking is accomplished through a 2-input NOR gate permitting one input to be used as a clock inhibit function. Holding either of the clock inputs high inhibits clocking, and holding either clock input low with the Shift/Load input high enables the other clock input. Data transfer occurs on the positive going edge of the clock. Parallel loading is inhibited as long as the Shift/Load input is high. When taken low, data at the parallel inputs is loaded directly into the register independent of the state of the clock.Features• Outputs Source/Sink 24 mA• HD74ACT165 has TTL-Compatible InputsHD74AC165/HD74ACT1652Pin ArrangementLogic SymbolPin NamesA to H Parallel Inputs S I Serial Input CP Clock Input S LShift Load Clock Inhibit Clock Inhibit Q H , Q HOutputsHD74AC165/HD74ACT1653Truth TableInputsClockParallel Internal Outputs Outputs S L Inhibit CP S I A ······ H Q A Q B Q H L X X X a ······ h a b h H L LX X Q A D Q B O Q HO HL H X H Q An Q Gn HL L X L Q An Q Cn H HXXXQ A DQ B OQ HOH :High Voltage Level L :Low Voltage Level X :Immaterial: Low-to-High Clock TransitionHD74AC165/HD74ACT1654Logic DiagramDC Characteristics (unless otherwise specified)ItemSymbol Max Unit ConditionMaximum quiescent supply current I CC 80µA V IN = V CC or ground, V CC = 5.5 V,Ta = Worst caseMaximum quiescent supply current I CC 8.0µA V IN = V CC or ground, V CC = 5.5 V,Ta = 25°CMaximum additional I CC /input (HD74ACT165)I CCT1.5mAV IN = V CC – 2.1 V, V CC = 5.5 V,Ta = Worst caseHD74AC165/HD74ACT1655AC Characteristics: HD74AC165Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pF ItemSymbol V CC (V)*1Min Typ Max Min Max Unit Maximum count f max3.385——70—MHzfrequency 5.0100——90—Propagation delay t PLH 3.3 1.011.017.5 1.020.5ns CP to Q H or Q H 5.0 1.08.011.5 1.013.5Propagation delay t PHL 3.3 1.012.018.0 1.021.5ns CP to Q H or Q H 5.0 1.08.512.5 1.014.5Propagation delay t PLH 3.3 1.013.519.5 1.022.5ns H to Q H or Q H 5.0 1.09.513.5 1.015.5Propagation delay t PHL 3.3 1.09.014.0 1.016.5ns H to Q H or Q H 5.0 1.0 6.59.5 1.011.0Propagation delay t PLH 3.3 1.011.520.5 1.023.5ns S L to Q H or Q H 5.0 1.08.514.0 1.016.0Propagation delay t PHL 3.3 1.010.016.5 1.019.5ns S L to Q H or Q H 5.01.07.511.01.012.5Note:1.Voltage Range 3.3 is 3.3 V ± 0.3 VVoltage Range 5.0 is 5.0 V ± 0.5 VHD74AC165/HD74ACT1656AC Operating Requirements: HD74AC165Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pFItemSymbol V CC (V)*1Typ Guaranteed MinimumUnit Setup time, HIGH or LOW t su3.3 3.5 5.0 6.0nsH to S L5.0 2.5 4.0 4.5Hold time, HIGH or LOW t h3.3–1.00.50.5ns H to S L5.0–0.50.50.5Setup time, HIGH or LOW t su 3.3 1.0 3.5 4.0ns S in to CP5.00.5 3.0 3.5Hold time, HIGH or LOW t h 3.3 1.5 2.0 2.0ns S in to CP5.0 1.0 2.0 2.0Setup time, HIGH or LOW t su 3.3 3.0 5.06.0ns S L to CP5.0 2.0 4.0 4.5Hold time, HIGH or LOW t h 3.3–2.00.00.0ns S L to CP5.0–1.00.00.0Recovery time clock inhibit t rec 3.3 2.5 3.5 3.5ns to CP5.0 2.0 3.0 3.0Clock pulse width t w 3.3 3.0 5.57.0ns 5.03.04.55.0Note:1.Voltage Range 3.3 is 3.3 V ± 0.3 VVoltage Range 5.0 is 5.0 V ± 0.5 VHD74AC165/HD74ACT1657AC Characteristics: HD74ACT165Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pF ItemSymbol V CC (V)*1Min Typ Max Min Max Unit Maximum count frequency f max 5.070——60—MHz Propagation delay CP to Q H or Q H t PLH 5.0 1.08.513.5 1.015.5ns Propagation delay CP to Q H or Q H t PHL 5.0 1.09.514.0 1.016.5ns Propagation delay H to Q H or Q H t PLH 5.0 1.010.513.5 1.015.5ns Propagation delay H to Q H or Q H t PHL 5.0 1.07.511.0 1.012.5ns Propagation delay S L to Q H or Q H t PLH 5.0 1.09.515.0 1.018.0ns Propagation delay S L to Q H or Q H t PHL5.01.08.513.01.015.5nsNote:1.Voltage Range 5.0 is 5.0 V ± 0.5 VHD74AC165/HD74ACT1658AC Operating Requirements: HD74ACT165Ta = +25°C C L = 50 pFTa = –40°C to +85°C C L = 50 pFItemSymbol V CC (V)*1Typ Guaranteed MinimumUnit Setup time, HIGH or LOW H to S Lt su 5.0 3.0 4.0 4.5ns Hold time, HIGH or LOW H to S Lt h 5.0–1.00.00.0ns Setup time, HIGH or LOW S in to CPt su 5.00.5 3.0 3.5ns Hold time, HIGH or LOW S in to CPt h 5.00.5 2.0 2.0ns Setup time, HIGH or LOW S L to CPt su 5.0 2.0 4.0 4.5ns Hold time, HIGH or LOW S L to CPt h 5.0–1.50.00.0ns Recovery time clock inhibit to CPt rec 5.0 2.0 3.0 3.0ns Clock pulse width t w5.03.57.08.0nsNote:1.Voltage Range 5.0 is 5.0 V ± 0.5 VCapacitanceItemSymbol Typ Unit Condition Input capacitanceC IN 4.5pF V CC = 5.5 V Power dissipation capacitanceC PD50pFV CC = 5.0 VHD74AC165/HD74ACT165 Package Dimensions9HD74AC165/HD74ACT16510HD74AC165/HD74ACT16511Cautions 1.Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent,copyright, trademark, or other intellectual property rights for information contained in this document.Hitachi bears no responsibility for problems that may arise with third party’s rights, includingintellectual property rights, in connection with use of the information contained in this document.2.Products and product specifications may be subject to change without notice.

HD74ALVCH16237316-bit Transparent D-type Latches with 3-state OutputsADE-205-179 (Z)Preliminary1st. EditionDecember 1996 DescriptionThe HD74ALVCH162373 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can be used as two 8-bit latches or one 16-bit latch. When the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level. All outputs, which are designed to sink up to 12 mA, include 26Ω resistors to reduce overshoot and undershoot.Features• V CC = 2.3 V to 3.6 V• Typical V OL ground bounce < 0.8 V (@V CC = 3.3 V, Ta = 25°C)• Typical V OH undershoot > 2.0 V (@V CC = 3.3 V, Ta = 25°C)• High output current ±12 mA (@V CC = 3.0 V)• Bus hold on data inputs eliminates the need for external pullup / pulldown resistors• All outputs have equivalent 26 Ω series resistors, so no external resistors are required.HD74ALVCH1623732Function TableInputs Output QOE LE D L H H H L H L L L L X Q 0 *1HXXZ H : High level L : Low level X : ImmaterialZ : High impedanceNote: 1.Output level before the indicated steady state input conditions were established.HD74ALVCH162373 Pin Arrangement3HD74ALVCH1623734Absolute Maximum RatingsItemSymbol Ratings Unit ConditionsSupply voltage V CC –0.5 to 4.6V Input voltage *1V I –0.5 to 4.6V Output voltage *1, 2V O –0.5 to V CC +0.5V Input clamp current I IK –50mA V I < 0Output clamp current I OK ±50mA V O < 0 or V O > V CC Continuous output current I O ±50mAV O = 0 to V CC ±100Maximum power dissipation at Ta = 55°C (in still air) *3P T 0.85W TSSOPStorage temperature Tstg–65 to 150°CNotes:Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

After the multivibrator has been retrigger ed com-parator C1and C2start operating and Qn is turned on.Cx then discharges through Qn.The voltage at the node R/C external falls.When it reaches V REFL the output of comparator C1 becomes low.This in turn resets the flip-flop and Qn is turned off.At this point C1stops functioning but C2continues to operate.The voltage at R/C external begins to rise with a time constant set by the external components Rx,Cx. Triggering the multivibrator causes Q to go high after internal delay due to the flip-flop and the gate.Q re-mains high until the voltage at R/C external rises again to V REFH.At this point C2output goes low and O goes low.C2stop operating.That means that after triggering when the voltage R/C external re-turns to V REFH the multivibrator has returned to its MONOSTABLE STATE.In the case where Rx⋅Cx are large enough and the discharge time of the ca-pacitor and the delay time in the I.C.can be ignored, the width of the output pulse tw(out)is as follows: t W(OUT)=0.46Cx⋅Rx(HC123)t W(OUT)=Cx⋅Rx(HC123A)M54/M74HC123/123A3/14FUNCTIONAL DESCRIPTION(continued)RE-TRIGGERED OPERATIONWhen a second trigger pulse follows the first its ef-fect will depend on the state of the multivibrator.If the capacitor Cx is being charged the voltage level of R/C external falls to Vrefl again and Q remains high i.e.the retrigger pulse arrives in a time shorter than the period Rx⋅Cx seconds,the capacitor charging time constant.If the second trigger pulse is very close to the initial trigger pulse it is ineffective ;i.e.the second trigger must arrive in the capacitor discharge cycle to be ineffective;Hence the mini-mum time for a second trigger to be effective de-pends on V CC and Cx.RESET OPERATIONCL is normally high.If CL is low,the trigger is not ef-fective because Q output goes low and trigger con-trol flip-flop is reset.Also transistor Op is turned on and Cx is charged quicky to V CC.This means if CL input goes low,the IC becomes waiting state both in operating and non operatin g state.TRUTH TABLEINPUTS OUTPUTSNOTEA B CL Q QH H OUTPUT ENABLEX L H L H INHIBITH X H L H INHIBITL H OUTPUT ENABLE L H OUTPUT ENABLE X X L L H INHIBITX:Don’t Care Z:High ImpedanceINPUT AND OUTPUT EQUIVALENT CIRCUITM54/M74HC123/123A4/14PIN DESCRIPTIONPIN No SYMBOL NAME AND FUNCTION 1,91A,2A Trigger Inputs(NegativeEdge Triggered) 2,101B,2B Trigger Inputs(PositiveEdge Triggered)3,111CLR,2CLR Direct Reset LOW and Trigger Action at Positive Edge4,121Q,2Q Outputs(Active LOW) 72R EXT/C EXT External ResistorCapacitor Connection 13,51Q,2Q Outputs(Active HIGH)14,61C EXT2C EXT External Capacitor Connection151R EXT/C EXT External ResistorCapacitor Connection8GND Ground(0V)16V CC Positive Supply VoltageIEC LOGIC SYMBOLABSOLUTE MAXIMUM RATINGSymbol Parameter Value Unit V CC Supply Voltage-0.5to+7V V I DC Input Voltage-0.5to V CC+0.5V V O DC Output Voltage-0.5to V CC+0.5VI IK DC Input Diode Current±20mAI OK DC Output Diode Current±20mAI O DC Output Source Sink Current Per Output Pin±25mAI CC or I GND DC V CC or Ground Current±50mAP D Power Dissipation500(*)mW T stg Storage Temperature-65to+150o C T L Lead Temperature(10sec)300o C Absolute Maximum Ratings are those values beyond whichdamage to the device may occu r.Functiona l ope ration und er these cond ition isnotimplied.

HD74AC123ADual Retriggerable Resettable MultivibratorREJ03D0245–0200Z(Previous ADE-205-365 (Z))Rev.2.00 Jul.16.2004DescriptionEach half of the HD74AC123A features retriggerable capability, complementary dc level triggering and overriding Direct Clear. When a circuit is in the quasi-stable (delay) state, another trigger applied to the inputs (per the Truth Table) will cause the delay period to start again, without disturbing the outputs. By repeating this process, the output pulse period (Q High, Q Low) can be made as long as desired. Alternatively, a delay period can be terminated at any time by a Low signal on C D , which also inhibits triggering. An internal connection from C D to the input gate makes it possible to trigger the circuit by a positive-going signal on C D , as shown in the Truth Table. For timing capacitor values greater than 1000 pF, the output pulse width is defined as follows. Where t w is in ns, R X is in k Ω and C X is in pF. t w = R X C XFeatures• Outputs Source/Sink 24 mA• Ordering InformationPart Name Package Type Package Code Package Abbreviation Taping Abbreviation (Quantity) HD74AC123APDIP-16 pinDP-16E, -16FV P —HD74AC123AFPEL SOP-16 pin (JEITA)FP-16DAVFP EL (2,000 pcs/reel) HD74AC123ARPEL SOP-16 pin (JEDEC) FP-16DNVRPEL (2,500 pcs/reel)Notes: 1.
