SYNCHRONOUS PRESETTABLE
BINARY COUNTER
The MC74F161A and MC74F163A are high-speed synchronous modu-
lo-16 binary counters. They are synchronously presettable for application in
programmable dividers and have two types of Count Enable inputs plus a Ter-
minal Count output for versatility in forming synchronous multistage counters.
The MC74F161A has an asynchronous Master Reset input that overrides all
other inputs and forces the outputs LOW. The MC74F163A has a Synchro-
nous 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 Frequency of 120 MHz
