Intended originally to drive thermal printheads, the A6832 has been
optimized for low output-saturation voltage, high-speed operation,
and pin configurations that are the 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 125 mA peak current. The combination of bipolar and
MOS technologies gives the A6832 arrays an interface flexibility
beyond the reach of standard buffers and power driver circuits.
The devices each have 32 bipolar npn open-collector saturated driv-
ers, a CMOS data latch for each of the drivers, two 16-bit CMOS shift
registers, and CMOS control circuitry. The high-speed CMOS shift reg-
isters and latches allow operation with most microprocessor-based sys-
tems. 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 A6832 is supplied in a 44-lead plastic leaded chip carrier (package
suffix EP), for surface-mount applications requiring minimum area. These
devices are lead (Pb) free, with 100% matte tin plated leadframes.
