54ACT169 - 4-Stage Synchronous Bidirectional Counter

Download the 54ACT169 datasheet PDF. This datasheet also covers the 54AC169 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.

Description

The ’AC/’ACT169 is fully synchronous 4-stage up/down counter.

The ’AC/’ACT169 is a modulo-16 binary counter.

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-to-HIGH transition of the Clock. n n n n n n Synchronous counting and loading Built-In lookahead carry capability Presettable for programmable operation Outputs source/sink 24 mA ’ACT has TTL-compatible inputs Standard Microcircuit Drawing (SMD) 5962-91603 Features n ICC reduc.
