s HIGH NOISE IMMUNITY:

VNIH = VNIL = 28 % VCC (MIN.)

s SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 4mA (MIN)

s BALANCED PROPAGATION DELAYS:

tPLH ≅ tPHL

s WIDE OPERATING VOLTAGE RANGE:

VCC (OPR) = 2V to 6V

s PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 4020

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.
