DESCRIPTION

The M74HC4040 is an high speed CMOS 12

STAGE BINARY COUNTER fabricated with

silicon gate C2MOS technology.

A clear input is used to reset the counter to the all

low level state. A high level on CLEAR

accomplishes the reset function. A negative

transition on the CLOCK input increments the

counter by one.

For M74HC4040 each division stage has an

output; the final frequency is 1/4096 fIN.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
