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 multiplexed LED displays or incandescent lamps within their 125 mA peak
output current rating. The combination of bipolar and MOS technologies 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°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.
