CD4017BM/CD4017BC Decade Counter/Divider

with 10 Decoded Outputs

CD4022BM/CD4022BC Divide-by-8 Counter/Divider

with 8 Decoded Outputs

General Description

The CD4017BM/CD4017BC is a 5-stage divide-by-10 John-

son counter with 10 decoded outputs and a carry out bit.

Features

Wide supply voltage range

3.0V to 15V

0.45 V (typ.)

High noise immunity

Low power

TTL compatibility

Fan out of 2 driving 74L

or 1 driving 74LS

The CD4022BM/CD4022BC is a 4-stage divide-by-8 John-

son counter with 8 decoded outputs and a carry-out bit.

Medium speed operation

5.0 MHz (typ.)

with 10V V

These counters are cleared to their zero count by a logical

‘‘1’’ on their reset line. These counters are advanced on the

positive edge of the clock signal when the clock enable sig-

nal is in the logical ‘‘0’’ state.

Low power

10 mW (typ.)

Fully static operation

The configuration of the CD4017BM/CD4017BC and

CD4022BM/CD4022BC permits medium speed operation

and assures a hazard free counting sequence. The 10/8

decoded outputs are normally in the logical ‘‘0’’ state and go

to the logical ‘‘1’’ state only at their respective time slot.

Each decoded output remains high for 1 full clock cycle.

The carry-out signal completes a full cycle for every 10/8

clock input cycles and is used as a ripple carry signal to any

succeeding stages.
