The HCF4022B HCF4022B is 4-stage Johnson counter having 8 decoded outputs. 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. This counter is advanced one count at the positive clock signal transition if the CLOCK INHIBIT signal is low. Counter advanced via the clock line is inhibited DIP SOP ORDER CODES PACKAGE TUBE T&R DIP SOP HCF4022BEY HCF4022BEY HCF4022BM1 HCF4022BM1 HCF4022M013TR HCF4022M013TR 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 gating and spike-free decoded outputs. Anti-lock gating 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 cycle every 8 clock input cycles and is used to ripple-clock the succeeding device in a multi-device counting chain.
