Applications
- Thermal printheads
- Multiplexed LED displays
- Incandescent lamps
Description
Designed to reduce logic supply current, chip size, and system cost, the A6833 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 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 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. Use of these drivers with TTL may require input pull-up resistors 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.
