DESCRIPTION
The M74HC4040 is an high speed CMOS 12
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 M74HC4040 each division stage has an
output; the final frequency is 1/4096 f
IN
.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
