Synchronous Presettable Binary Counter

General Description

The AC161 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 AC161 has an asynchronous Master Reset input that overrides all other

inputs and forces the outputs LOW.

Note 1: Absolute maximum ratings are those values beyond which damage to the device may

occur. The databook specifications should be met, without exception, to ensure that

the system design is reliable over its power supply, temperature, and output/input

loading variables. National does not recommend operation of FACT TM circuits outside

databook specifications.
