DESCRIPTION

The

M74HC294

is

an

high

speed

CMOS

PROGRAMMABLE DIVIDER/TIMER fabricated

This device is a programmable frequency divider

and has two clock inputs, either one may be used

for clock gating. (see the function table).

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.
