DESCRIPTION The HCF4017Bis a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. The HCF4017B is 5-stage Johnson counter having 10 decoded outputs. Inputsinclude 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 isadvanced one count at the positive clock signal transition if the CLOCK INHIBIT signal is low. Counter advanced via the clock line is inhibited
when the CLOCK INHIBIT signal is high. A high RESETsignal 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 gatingis 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 clockcycle. A CARRY - OUT signal completes one cycle every 10 clock input cycles and is used to ripple-clock the succeeding device in a multi-device counting chain.
