A6821SLW-T Description

Short technical summary and product information.

The Allegro Microsystems A6821SLW-T is an 8-bit serial input latched sink driver that combines bipolar and MOS technology for flexible interface capabilities. It is suitable for driving multiplexed LED displays or incandescent lamps.

 

Key electrical specifications include a logic supply range of 3.3V to 5V and a per-channel output current of 500mA. The device features an 8-bit CMOS shift register, CMOS control circuitry, 8 CMOS data latches, and 8 bipolar current-sinking Darlington output drivers. Its inputs are compatible with standard CMOS logic levels and may require pull-up resistors for TTL circuits. The drivers can be cascaded using the serial data output for applications requiring additional drive lines.

 

This component operates within an ambient temperature range of -20°C to 85°C and is supplied in a 16-lead wide-body SOIC package, making it suitable for surface-mount applications. The device also includes features such as power-on reset (POR), a data input rate of up to 10 MHz, and Schmitt trigger inputs for improved noise immunity.

 

Designed for reliability, the A6821SLW-T is lead (Pb) free with 100% matte tin plated leadframes. Its merged bipolar and MOS technology provides an interface flexibility beyond standard logic buffers and power driver arrays.
