DESCRIPTION

The M74HC4020 is an high speed CMOS 14
STAGE BINARY COUNTER fabricated with
silicon gate C

2

MOS 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 f

at clock.
