5832
BiMOS II 32-BIT SERIAL-INPUT, LATCHED DRIVERS
Intended originally to drive thermal printheads, the UCN5832A and UCN5832EP have been optimized for low output-saturation voltage, high-speed operation, and pin configurations most convenient for the tight space requirements of high-resolution printheads. These integrated circuits can also be used to drive multiplexed LED displays or incandescent lamps at up to 150 mA peak current. The combination of bipolar and MOS technologies gives BiMOS II arrays an interface flexibility beyond the reach of standard buffers and power driver circuits. The devices each have 32 bipolar NPN open-collector saturated drivers, a CMOS data latch for each of the drivers, two 16-bit CMOS shift registers, and CMOS control circuitry. The high-speed CMOS shift registers and latches allow operation with most microprocessor based systems. Use of these drivers with TTL may require input pull-up resistors to ensure an input logic high. MOS serial data outputs permit cascading for interface applications requiring additional drive lines. The UCN5832A is supplied in a 40-pin dual in-line plastic package with 0.600" (15.24 mm) row spacing. Under normal operating conditions, this device will allow all outputs to sustain 100 mA continuously without derating. The UCN5832EP is supplied in a 44-lead plastic leaded chip carrier for minimum area, surface-mount applications. Both devices are also available for operation from -40C to +85C. To order, change the prefix from `UCN' to `UCQ'. Similar 32-bit serial-input latched source drivers are available as the UCN5818AF/EPF. Other high-voltage, high-current 8-bit devices are available as the UCN5821A, UCN5841A/LW, and UCN5842A.

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 OUTPUT ENABLE input be low during serial data entry. When the OUTPUT ENABLE input is low, all of the output buffers are disabled (OFF) without affecting the information stored in the latches or shift register. With the OUTPUT ENABLE input high, the outputs are controlled by the state of the latches.
