The Allegro Microsystems A6841SA-T is an 8-bit serial input latched sink driver designed for peripheral power driver applications. It integrates an eight-bit CMOS shift register, control circuitry, data latches, and eight bipolar current-sinking Darlington output drivers. Each output can sink up to 500 mA and has an integral transient-suppression diode, making it suitable for driving relays, solenoids, and other inductive loads.
The device operates with a logic supply range of 3.3V to 5.5V and features CMOS and TTL compatible inputs with Schmitt trigger for improved noise immunity. The output breakdown voltage is rated at a minimum of 50V (35V sustaining). Drivers can be cascaded using the serial data output for applications requiring additional drive lines. The A6841SA-T is provided in an 18-pin DIP package suitable for through-hole mounting.
Key features include power-on reset (POR), a data input rate up to 10 MHz, and single or split supply operation. The outputs are high-voltage current-sink type with internal pull-up/pull-down resistors. The operating temperature range is -20°C to 85°C.
