BiMOS II 32-BIT SERIAL-INPUT,

LATCHED DRIVER

Designed to reduce logic supply current, chip size, and system

cost, the UCN5833A/EP integrated circuits offer high-speed operation

for thermal printers. These devices can also be used to drive multi-

plexed LED displays or incandescent lamps within their 125 mA peak

output current rating. The combination of bipolar and MOS technolo-

gies gives BiMOS II smart power ICs an interface flexibility beyond the

reach of standard buffers and power driver circuits.

UCN5833EP

These 32-bit drivers have bipolar open-collector npn Darlington

outputs, a CMOS data latch for each of the drivers, a 32-bit CMOS

shift register, and CMOS control circuitry. The high-speed CMOS shift

registers and latches allow operation with most microprocessor-based

systems at data input rates above 3.3 MHz. Use of these drivers with

TTL may require input pull-up resistors to ensure an input logic high.

The UCN5833A is supplied in a 40-pin dual in-line plastic package

with 0.600" (15.24 mm) row spacing. At an ambient temperature of

+75°C, all outputs of the DlP-packaged device will sustain 50 mA

continuously. For high-density applications, the UCN5833EP is

available. This 44-lead plastic chip carrier (quad pack) is intended

for surface-mounting on solder lands with 0.050" (1.27 mm) centers.

CMOS serial data outputs permit cascading for applications requiring

additional drive lines.
