DESCRIPTION
The M74HC4024 is an high speed CMOS 7
STAGE BINARY COUNTER fabricated with
silicon gate C
2
MOS technology.
This devices is incremented on the falling edge
(negative transition) of the input clock, and all its
outputs are reset to a low level by applying a
logical high level on their reset input (CLEAR).
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
