74ACT169 - 4-Stage Synchronous Bidirectional Counter

Download the 74ACT169 datasheet PDF. This datasheet also covers the 74AC169 variant, as both devices belong to the same 4-stage synchronous bidirectional counter family and are provided as variant models within a single manufacturer datasheet.

General Description

The ’AC ’ACT169 is fully synchronous 4-stage up down counter The ’AC ’ACT169 is a modulo-16 binary counter It

Key Features

  • a preset capability for programmable operation carry lookahead for easy cascading and a U D input to control the direction of counting All state changes whether in counting or parallel loading are initiated by the LOW-toHIGH transition of the Clock Features Y ICC reduced by 50% Y Synchronous counting and loading Y Built-In lookahead carry capability Y Presettable for programmable operation Y Outputs source sink 24 mA Y ’ACT has TTL-compatible inputs Y Standard Military Drawing (SMD) ’AC169 5962.
