Divide-by-8 Counter/Divider with 8 Decoded Outputs
General Description
The CD4017BC is a 5-stage divide-by-10 Johnson counter
with 10 decoded outputs and a carry out bit.
The CD4022BC is a 4-stage divide-by-8 Johnson 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 CD4017BC and CD4022BC per-
mits medium speed operation and assures a hazard free
counting sequence. The 10/8 decoded outputs are nor-
mally 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.
