74F161A, 74F163A

Synchronous Presettable Binary Counter

Features

General Description

■ Synchronous counting and loading

■ High-speed synchronous expansion

■ Typical count frequency of 120MHz

The 74F161A and 74F163A are high-speed synchro-

nous modulo-16 binary counters. They are synchro-

nously 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 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 simulta-

neously reset on the rising edge of the clock. The

74F161A and 74F163A are high-speed versions of the

74F161 and 74F163.
