74F161A
74F163A
Synchronous Presettable Binary Counter
General Description
The 74F161A and 74F163A are high-speed synchronous
modulo-16 binary counters. They are synchronously pre-
settable for application in programmable dividers and have
two types of Count Enable inputs plus a Terminal Count
output for versatility in forming synchronous multi-stage
counters. The 74F161A has an asynchronous Master-
Reset input that overrides all other inputs and forces the
outputs LOW. The 74F163A 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. The 74F161A and 74F163A are high-
speed versions of the 74F161 and 74F163.
