DESCRIPTION
The M74HC4020 is an high speed CMOS 14
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 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.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + I CC/2 (per FLIP/
FLOP)
