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 condi-

tions, 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 are available as

the UCN5818AF/EPF. Other high-voltage, high-current 8-bit devices

are available as the UCN5821A, UCN5841A/LW, and UCN5842A.
