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
The CD4022BM CD4022BC is a 4-stage divide-by-8 John-
son counter with 8 decoded outputs and a carry-out bit
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
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
