FEATURES

APPLICATIONS

Use the following complete part numbers when ordering:

A merged combination of bipolar and MOS technology gives these

devices an interface ﬂ exibility beyond the reach of standard logic

buffers and power driver arrays. Typical applications include driving

multiplexed LED displays or incandescent lamps.

The A6821 has an eight-bit CMOS shift register and CMOS control

circuitry, eight CMOS data latches, and eight bipolar current-sinking

Darlington output drivers.

The CMOS inputs are compatible with standard CMOS logic levels.

TTL circuits may require the use of appropriate pull-up resistors. By

using the serial data output, the drivers can be cascaded for interface

applications requiring additional drive lines.

The A6821SA is furnished in a standard 16-pin plastic DIP. The

A6821EA is a 16-pin plastic DIP, capable of operation from -40°C to

+85°C. The A6821SLW is a 16-lead wide-body SOIC, for surface-

mount applications. These devices are lead (Pb) free, with 100% matte

tin plated leadframes.
