Dwg. No. -12,659 Caution: CMOS devices have input static protection but are susceptible to damage when exposed to extremely high static electrical charges. The merging of low-power CMOS logic and bipolar output power drivers permit the UCN5841/42 and 5841SLW integrated circuits to be used in a wide variety of peripheral power driver applications. The three devices in this series 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 500 m NPN Darlington outputs, with integral transient-suppression diodes, are suitable for use with relays, solenoids, and other inductive loads. Except for the maximum driver output voltage ratings, the UCN5841, 5841SLW, and UCN5842 are identical. The UCN5842 offers premium performance with a minimum output-breakdown voltage rating of 80 V (50 V sustaining). ll drivers can be operated with a split supply where the negative supply is up to -20 V. BiMOS II devices have higher data-input rates than the earlier 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, drivers can be cascaded for interface applications requiring additional drive lines. Suffix devices are furnished in a standard 18-pin plastic DIP; suffix LW indicates a 20-lead wide-body SOIC.

EP Serial Data present at the input is transferred to the shift register on the logic 0 to logic 1 transition of the CLOCK input pulse. On succeeding CLOCK pulses, the registers shift data information towards the SERIL DT OUTPUT. The SERIL DT 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 conversion). The latches will continue to accept new data as long as the STROBE is held high. pplications where the latches are bypassed (STROBE tied high) will require that the ENBLE input be high during serial data entry. When the ENBLE input is high, all of the output buffers are disabled (OFF) without affecting the information stored in the latches or shift register. With the ENBLE input low, the outputs are controlled by the state of the latches. 115 Northeast Cutoff, Box Worcester, Massachusetts (508)
