FACT DATA
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.
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
