The HCC/HCF4017B and HCC/HCF4022B 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 pro- vides pulse shaping that allows unlimited clock input pulse rise and fall times. These counters are ad- vanced one count at the positive clock signal tran- sition 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 decade-counter configuration permits high-speed operation, 2-input decimal-decode gat- ing, and spike-free decoded outputs. Anti-lock gat- ing is provided, thus assuring proper counting sequence. The decoded outputs are normally low and go high only at their respective decoded time slot. Each decoded output remains high for one full clock cycle. A CARRY-OUT signal completes one 1/12 |
