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.

Speed Synchronous Expansion
Typical Count Rate of 125 MHz
Outputs Source/Sink 24 mA
