Allegro A6841 DABiC-5 8-Bit Serial Input Latched Sink Drivers Datasheet

The A6841 is an 8‑bit serial input latched sink driver that combines low‑power CMOS logic with bipolar Darlington output drivers. It provides up to 500 mA per output and is suitable for driving relays, solenoids and other inductive loads. The device includes a CMOS shift register, data latches, and high‑voltage current‑sink outputs with built‑in transient‑suppression diodes.

The part is offered in three package types—18‑pin DIP, 18‑pin wide‑body SOIC, and 20‑pin wide‑body SOIC—each sharing identical electrical characteristics. Key specifications include a 3.3 V–5 V logic supply range, ±0.3 V input range, 10 MHz maximum clock frequency, and an operating temperature range of –40 °C to +85 °C. Detailed pin assignments, timing diagrams, and power‑dissipation curves are provided for design reference.
