DESCRIPTION

The M74HC7292 is an high speed CMOS

PROGRAMMABLE DIVIDER/TIMER fabricated

with silicon gate C2MOS technology.

This device is a programmable frequency divider

and have two clock inputs, either one may be used

for clock gating. (see the function table).The

M74HC7292 can divide from 22 to 231. This

device feature an active-low clear input to initialize

the state of all flip-flops. To facilitate incoming

inspection, test points (TP1, TP2, TP3) are

provided. All inputs are equipped with protection

circuits against static discharge and transient

excess voltage.
