The M74HC4020 is an high speed CMOS 14 ST AGE 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 M74HC4020 twelve kind of divided output are provided; 1st and 4th stage to 14th stage.
The maximum division available at last stage is 1/16384 x fIN at clock.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.
