Overview

MC74AC161, MC74ACT161, MC74AC163, MC74ACT163 Synchronous Presettable Binary Counter The MC74AC161/74ACT161 and MC74AC163/74ACT163 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 MC74AC161/74ACT161 has an asynchronous Master Reset input that overrides all other inputs and forces the outputs LOW.
The MC74AC163/74ACT163 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 • ′ACT161 and ′ACT163 Have TTL Compatible Inputs • These are Pb−Free Devices VCC TC Q0 Q1 Q2 Q3 CET PE 16 15 14 13 12 11 10 9 www.
