The A6279EA-T from Allegro MicroSystems is a BiCMOS device designed for LED display applications. It integrates a CMOS shift register, data latches, and NPN constant-current sink drivers, providing 16 output lines.
This LED driver IC supports direct interfacing with microprocessor-based systems, with typical serial data input rates up to 25 MHz when using a 3.3 or 5 V logic supply. The LED drive current is user-selectable via a single resistor, with outputs capable of sinking up to 90 mA. Features include Schmitt trigger inputs for noise immunity, power-on reset, and LED open circuit detection.
The A6279EA-T is available in a 24-DIP through-hole package. All packages are lead-free with 100% matte tin plated leadframes. The device includes internal UVLO and thermal shutdown circuitry for protection.
