Synchronous Presettable Binary Counter
General Description
The ’F161A and ’F163A 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 multi-stage counters The ’F161A has an asynchronous Master-Reset input that overrides 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
