Synchronous Presettable Binary Counter
General Description
The AC/ACT161 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
AC/ACT161 has an asynchronous Master Reset input that
overrides all other inputs and forces the outputs LOW.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
