The cd4017bc is a 5-stage divide-by-10 Johnson counter with 10 decoded outputs and a carry out bit. This counter is cleared to its zero by a logical" 1 inch on its reset line. This counter is advanced on the positive edge of the clock signal when the clock enable signal is in the logical" 0 inch state. The configuration permits medium speed operation and assures a hazard-free counting sequence. The 10/8 decoded outputs are normally in the logical" 0 inch state and go to the logical" 1 inch 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.
