Synchronous Presettable Binary Counter
74F161A • 74F163A Synchronous Presettable Binary Counter April 1988 Revised September 2000 74F161A 74F163A Synchronous Presettable Binary Counter General Description Features The 74F161A and 74F163A are high-speed synchronousSynchronous counting and loading modulo-16 binary counters. They are synchronously pre-High-speed synchronous expansion settable for application in programmable dividers and have Typical count frequency of 120 MHz 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.
