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.

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擄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.
