CD4017BC CD4022BC
Decade Counter/Divider with 10 Decoded Outputs
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.

Note 1: "Absolute Maximum Ratings" are those values beyond which the
safety of the device cannot be guaranteed, they are not meant to imply that
the devices should be operated at these limits. The table of "Recom-
mended Operating Conditions" and "Electrical Characteristics" provides
conditions for actual device operation.
