DESCRIPTION

The M74HC4017 is an high speed CMOS

DECADE COUNTER/DIVIDER fabricated with

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 for one clock period of the

10 clock period cycle. The CARRY output goes

low to high after OUTPUT 10 goes low, and can

be used in conjunction with the CLOCK ENABLE

(CKEN)to cascade several stages.

The CLOCK ENABLE input disables counting

when in the high state. 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.
