74AC163 74ACT163 Synchronous Presettable Binary Counter
General Description
The AC/ACT163 are high-speed synchronous modulo-16 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 AC/ACT163 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.
Features
s ICC reduced by 50% s Synchronous counting and loading s High-speed synchronous expansion s Typical count rate of 125 MHz s Outputs source/sink 24 mA s ACT163 has TTL-compatible inputs
