54F163A Datasheet Synchronous Presettable Binary Counter

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: Obsolete 54F 74F161A  54F 74F163A Synchronous Presettable Binary Counter November 1994 54F 74F161A  54F 74F163A Synchronous Presettable Binary Counter.

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

General Description

The ’F161A and ’F163A 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 ’F161A has an asynchronous Master-Reset input that overrides all other inputs and forces the outputs LOW The ’F163A has a Synchronous Reset input that overrides counting and parallel loading and allows the outputs to be simultaneously reset on the rising edge of the clock The ’F161A and ’F163A are high-speed versions of the ’F161 and ’F163

Key Features
