BiMOS II 8-BIT SERIAL-INPUT, LATCHED DRIVERS
The merging of low-power CMOS logic and bipolar output power drivers permit the UCN5841/42A, UCN5841/42LW, and A5841/42SLW integrated circuits to be used in a wide variety of peripheral power driver applications. Each device has an eight-bit CMOS shift register and CMOS control circuitry, eight CMOS data latches, and eight bipolar current-sinking Darlington output drivers. The 500 mA npn Darlington outputs, with integral transient-suppression diodes, are suitable for use with relays, solenoids, and other inductive loads. Except for packaging and the maximum driver output voltage ratings, the UCN5841A, UCN5841LW, A5841SLW, UCN5842A, UCN5842LW, and A5842SLW are identical. All package variations of the 5842 offer premium performance with a minimum output-breakdown voltage rating of 80 V (50 V sustaining). All 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. The UCN584xA devices are furnished in a standard 18-pin plastic DIP; the UCN584xLW devices are in an 18-lead surface-mountable wide-body SOIC package; the A584xSLW devices are provided in a 20lead wide-body SOIC package with improved thermal characteristics. The A5841SLW and UCN5841LW drivers are also available for operation to a temperature of -40C. To order, change the suffix from `SLW' to `ELW', or change the prefix from `UCN' to `UCQ'.

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 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 conversion). 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.
