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 UCN5832A and UCN5832EP 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 UCN5832A and UCN5832EP 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 of UCN5832A and UCN5832EP 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 -40°C to +85°C. To order, change the prefix from 'UCN' to 'UCQ'.

Similar 32-bit serial-input latched source drivers UCN5832A and UCN5832EP are available as the UCN5818AF/EPF. Other high-voltage, high-current 8-bit devices are available as the UCN5821A, UCN5841A/LW, and UCN5842A.
