MC74AC161, MC74ACT161, MC74AC163, MC74ACT163 Synchronous Presettable Binary Counter The MC74AC161/74ACT161 and MC74AC163/74ACT163 are highspeed synchronous modulo16 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 multistage counters. The MC74AC161/74ACT161 has an asynchronous Master Reset input that overrides all other inputs and forces the outputs LOW. The MC74AC163/74ACT163 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. http://onsemi.com 16 1 DIP16 N SUFFIX CASE 648 w Synchronous Counting and Loading HighSpeed Synchronous Expansion Typical Count Rate of 125 MHz Outputs Source/Sink 24 mA ′ACT161 and ′ACT163 Have TTL Compatible Inputs These devices are available in Pbfree package(s). Specifications herein apply to both standard and Pbfree devices.
