1 / 8 page © 2000 Fairchild Semiconductor Corporation DS009486 www.fairchildsemi.com April 1988 Revised September 2000 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. Features s Synchronous counting and loading s High-speed synchronous expansion s Typical count frequency of 120 MHz Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
