HD74ACT161/HD74ACT163
Synchronous Presettable Binary Counter
Description
The HD74ACT161 and HD74ACT163 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. The
HD74ACT161 have an asynchronous Master Reset input that overrides all other inputs and forces the
outputs Low. The HD74ACT163 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.
Features
Synchronous Counting and Loading
High-Speed Synchronous Expansion
Typical Count Rate of 125 MHz
Outputs Source/Sink 24 mA
HD74ACT161 and HD74ACT163 have TTL-Compatible Inputs
