FEATURES

APPLICATIONS

Use the following complete part numbers when ordering:

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

A6833 integrated circuits offer high-speed operation for thermal print-

ers. 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 the A6833

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 out-

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

registers and latches allow operation with most microprocessor-based

systems. Use of these drivers with TTL may require input pull-up resis-

tors to ensure an input logic high. CMOS serial data outputs permit

cascading for applications requiring additional drive lines.

The A6833 is supplied in a 44-lead plastic chip carrier (quad pack),

intended for surface mounting on solder lands with 0.050 in. (1.27 mm)

centers. These devices are lead (Pb) free, with 100% matte tin plated

leadframes.

3.3 V to 5 V logic supply range

To 10 MHz data input rate

30 V minimum output breakdown

Darlington current-sink outputs

Low-power CMOS logic and latches

Schmitt trigger inputs for improved noise immunity

Thermal printheads

Multiplexed LED displays

Incandescent lamps
