DESCRIPTION

The M74HC7294 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 M74HC7294 can divide from 22 to 215. This

device feature an active-low clear input to initialize
