CD4022 - Octal Divider Counter

The CD4022 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  CD4022 permits medium speed operation and assures a hazard free counting sequence. The 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 8 clock input cycles and is used as a ripple carry signal to any succeeding stages.

Features:

  • Wide supply voltage range 3.0V to 15V
