Product Summary

The 74AC161MTCX is a high-speed Synchronous Presettable Binary Counter. The 74AC161MTCX 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 74AC161MTCX has an asynchronous Master Reset input that overrides all other inputs and forces the outputs LOW.
