CMOS Counter/Dividers
CD4017BMS - Decade Counter with 10 Decoded Outputs CD4022BMS - Octal Counter with 8 Decoded Outputs CD4017BMS and CD4022BMS are 5-stage and 4-stage Johnson counters having 10 and 8 decoded outputs, respectively. Inputs include a CLOCK, a RESET, and a CLOCK INHIBIT signal. Schmitt trigger action in the CLOCK input circuit provides pulse shaping that allows unlimited clock input pulse rise and fall times. These counters are advanced one count at the positive clock signal transition if the CLOCK INHIBIT signal is low. Counter advancement via the clock line is inhibited when the CLOCK INHIBIT signal is high. A high RESET signal clears the counter to its zero count. Use of the Johnson counter configuration permits high speed operation, 2-input decode gating and spike-free decoded outputs. Anti-lock gating is provided, thus assuring proper counter sequence. The decoded output are normally low and go high only at their respective decoded time slot. Each decoded output remains high for one full clock cycle. A CARRYOUT signal completes one cycle every 10 clock input cycles in the CD4017BMS or every 8 clock input cycles in the CD4022BMS and is used to ripple-clock the succeeding device in a multi-device counting chain.
The CD4017BMS and CD4022BMS series types are supplied in these 16 lead outline packages

FIGURE 15. CASCADING THE CD4017BMS
When the Nth decoded output is reached (Nth clock pulse) the S-R flip-flop (constructed from two NOR gates of the CD4001B) generates a reset pulse which clears the CD4017BMS or CD4022BMS to its zero count. At this time, if the Nth decoded output is greater than or equal to 6 in the CD4017BMS or 5 in the CD4022BMS, the COUT line goes high to clock the next CD4017BMS or CD4022BMS counter section. The "0" 9
decoded output also goes high at this time. Coincidence of the clock low and decoded "0" output low resets the S-R flip-flop to enable the CD4017BMS or CD4022BMS. If the Nth decoded output is less than 6 (CD4017BMS) or 5 (CD4022BMS), the COUT line will not go high and, therefore, cannot be used. In this case "0" decoded output may be used to perform the clocking function for the next counter.
