CD4017B/CD4022B
■The CD4017B is a 5-stage divide-by-10 Johnson counter with 10 decoded outputs and a carry out bit. The CD4022B 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 CD4017B and CD4022B 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.
