DESCRIPTION
The M54/74HC4020/HC4040 are high speed
CMOS 14/12-STAGE BINARY COUNTER
fabricated in silicon gate C
2
MOS technology. They
have the same high speed performance of LSTTL
combined with true CMOS low consumption.
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 HC4020 twelve kind od divided output are
provided; 1st and 4th stage to 14th stage.

at clock.
For HC4040 each division stage has an output; the
final frequency is 1/4096 x f

.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
