DESCRIPTION
The M74HC294 is an high speed CMOS
PROGRAMMABLE DIVIDER/TIMER fabricated
with silicon gate C²MOS technology.
This device is a programmable frequency divider
and has two clock inputs, either one may be used
for clock gating. (see the function table).
The M74HC294 can divide from 2² to 2¹⁵. This
device feature an active-low clear input to initialize

the state of all flip-flops. To facilitate incoming
inspection, test points (TP) are provided. All
inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
This device has Q output with "Totem Pole"
configuration and test point TP with "Open Drain"
output configuration.
