MICROCIRCUIT DATA SHEET Original Creation Date: 07/02/96 Last Update Date: 03/17/97 Last Major Revision Date: 02/05/97 MN54ACT161-X REV 2A0 Synchronous Presettable Binary Counter General Description The ACT161 is a high-speed synchronous modulo-16 binary counter. It is synchronously presettable for application in programmable dividers and has two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multistage counters. The ACT161 has an asynchronous Master Reset Input that overrides all other inputs and forces the outputs LOW.
