BiMOS II 8-BIT SERIAL-INPUT,LATCHED DRIVERSAlways order by complete part number, e.g., UCN5821A .Data Sheet 26185.12E5821 AND 5822A merged combination of bipolar and MOS technology gives these devices an interface flexibility beyond the reach of standard logic buffers and power driver arrays. The UCN5821A,UCN5821LW, UCN5822A, and UCN5822LW each have an eight-bit CMOS shift register and CMOS control circuitry, eight CMOS data latches, and eight bipolar current-sinking Darlington output drivers. The UCN5821A/LW and UCN5822A/LW are identical except for rated output voltage.BiMOS II devices have much higher data-input rates than the original BiMOS circuits. With a 5 V logic supply, they will typically operate at better than 5 MHz. With a 12 V supply,significantly higher speeds are obtained. The CMOS inputs are compatible with standard CMOS and NMOS logic levels. TTL circuits may require the use of appropriate pull-up resistors. By using the serial data output, the drivers can be cascaded for interface applications requiring additional drive lines.The UCN5821/22A are furnished in a standard 16-pin plastic DIP; the UCN5821/22LW are in a 16-lead wide-body SOIC for surface-mount applications. The UCN5821A is also available for operation from -40°C to +85°C.

On succeeding CLOCK pulses, the registers shift data information towards the SERIAL DATA OUTPUT. The SERIAL DATA must appear at the input prior to the rising edge of the CLOCK input waveform.Information present at any register is transferred to its respective latch when the STROBE is high (serial-to-parallel con-version). The latches will continue to accept new data as long as the STROBE is held high. Applications where the latches are bypassed (STROBE tied high)will require that the ENABLE input be high during serial data entry.When the ENABLE input is high, all of the output buffers are disabled (OFF)without affecting the information stored in the latches or shift register. With the ENABLE input low, the outputs are controlled by the state of the latches.CLOCKDATA INSTROBEENABLE OUT5821 AND 58228-BIT SERIAL-INPUT,LATCHED DRIVERSNOTES: 1.Lead thickness is measured at seating plane or below.2.Lead spacing tolerance is non-cumulative.3.Exact body and lead configuration at vendor’s option within limits shown.Dwg.

EDI88512CA20CM中文资料
The EDI88512CA is a 4 megabit Monolithic CMOS Static RAM. The 32 pin DIP pinout adheres to the JEDEC evolutionary standard for the four megabit device. All 32 pin packages are pin for pin upgrades for the single chip enable 128K x 8, the EDI88128CS. Pins 1 and 30 become the higher order addresses. The 36 pin revolutionary pinout also adheres to the JEDEC standard for the four megabit device. The center pin power and ground pins help to reduce noise in high performance systems. The 36 pin pinout also allows the user an upgrade path to the future 2Mx8. A Low Power version with Data Retention (EDI88512LPA) is also available for battery backed applications. Military product is available compliant to Appendix A of MILPRF-38535.
