M74HC4040 12-Stage Binary Counter

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 anoutput; the final frequency is 1/4096 fIN.

All inputs are equipped with protection circuits against static discharge and transient excess voltage
