74F161A • 74F163A

Synchronous Presettable Binary Counter

General Description

Features

■ Synchronous counting and loading

■ High-speed synchronous expansion

■ Typical count frequency of 120 MHz

The 74F161A and 74F163A are high-speed synchronous

modulo-16 binary counters. They are synchronously pre-

settable 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 Master-

Reset input that overrides all other inputs and forces the

outputs LOW. The 74F163A 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 74F161A and 74F163A are high-

speed versions of the 74F161 and 74F163.
