CD4017BM  -  Decade Counter/Divider with 10 Decoded Outputs  -  National Semiconductor Corporation  -  Counter

General Description
The CD4017BM/CD4017BC is a 5-stage divide-by-10 Johnson counter with 10 decoded outputs and a carry out bit.
The CD4022BM/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 signal 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.
