PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 294

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.
