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 M54HC4020 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 f_IN at clock.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
