DESCRIPTION

The M74HC4017 is an high speed CMOS
DECADE COUNTER/DIVIDER fabricated with
silicon gate C

2

MOS technology.
The M74HC4017 is a 5-stage Johnson counter
with 10 decoded outputs. Each of the decoded
outputs is normally low and sequentially goes high
on the low to high transition of the clock input.
Each output stays high fo r one clock period of t he
10 clock period cycle. The CARRY output goes
low to high after OUTP UT 10 goes low, and can

The CLOCK ENABLE

input disables counting
when in the high st ate. A CLEAR (CLR) input is
also provided which when taken high sets all the
decoded outputs low.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
