54F 74F161A  54F 74F163A
Synchronous Presettable Binary Counter
General Description
The ’F161A and ’F163A 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 Terminal Count output for
versatility in forming synchronous multi-stage counters The
’F161A has an asynchronous Master-Reset input that over-
rides all other inputs and forces the outputs LOW The
’F163A 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
’F161A and ’F163A are high-speed versions of the ’F161
and ’F163
Features
Y Synchronous counting and loading
Y High-speed synchronous expansion
Y Typical count frequency of 120 MHz
Y Guaranteed 4000V minimum ESD protection
