DESCRIPTION

The 54/74HC292/7292 and HC294/7294 are high

speed CMOS PROGRAMMABLE DIVIDER/TIMER

fabricated with silicon C

They achieve the high speed operation similar to

equivalent LSTTL while maintaining the CMOS low

power dissipation.

These

devices are

programmable

frequency

dividers. The types have two clock inputs, either one

may be used for clock gating. (see the function

table). The HC292/7292 can divide from 2

and the HC294/7294 can divide from 2

types feature an active-low clear input to initialize

the state of all flip-flops. To facilitate incoming

inspection, test points are provided. (TP1, TP2 and

TP3

on

the

HC292/7292

and

TP on

the

HC294/7294).

All

inputs

are

equipped

with

protection circuits against static discharge and

transient excess voltage.

HC292/294 have Q output with ”Totem pole”

configuration and test point TP with ”Open Drain”

output configuration.

HC7292/7294 have all outputs ”Totem Pole”.
