74F163A Datasheet Synchronous Presettable Binary Counter

Manufacturer: Fairchild (now onsemi)

Overview: 74F161A • 74F163A Synchronous Presettable Binary Counter April 1988 Revised July 1999 74F161A • 74F163A Synchronous Presettable Binary Counter.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The 74F161A and 74F163A 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 multi-stage counters.

The 74F161A has an asynchronous MasterReset input that overrides all other inputs and forces the outputs LOW.
