54ACT161 - Synchronous Presettable Binary Counter

Download the 54ACT161 datasheet PDF. This datasheet also covers the 54AC161 variant, as both devices belong to the same synchronous presettable binary counter family and are provided as variant models within a single manufacturer datasheet.

Description

The ’AC/’ACT161 are high-speed synchronous modulo-16 binary counters.

They are synchronously presettable for application in programmable dividers and have two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multistage counters.

Features

  • n ICC reduced by 50% Logic Symbols Pin Names CEP CET CP MR P0.
  • P3 PE Q0.
  • Q3 TC DS100274-1.

They are synchronously presettable for application in programmable dividers and have two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multistage counters. The ’AC/ ’ACT161 has an asynchronous Master Reset input that overrides all other inputs and forces the outputs LOW.
