s SYMMETRICAL OUTPUT IMPEDANCE:
|I_OH| = I_OL = 4mA (MIN)
s BALANCED PROPAGATION DELAYS:
t_PLH ≅ t_PHL
s WIDE OPERATING VOLTAGE RANGE:
V_CC (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 f_IN at clock.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
