UCN5832A 40-Pin DIP
UCN5832EP 44-Lead PLCC
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 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 are available as
the UCN5818AF/EPF. Other high-voltage, high-current 8-bit devices
are available as the UCN5821A, UCN5841A/LW, and UCN5842A.
