Caution: CMOS devices have input-static protection,
but are susceptible to damage when exposed to
extremely high static-electrical charges.
A6821
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.
