CD4017B, CD4022B Types Product Overview

CD4017B and CD4022B are sequential logic circuits: a 5-stage and a 4-stage Johnson counter, respectively. CD4017B has 10 decoded outputs, while CD4022B has 8 decoded outputs. The circuits have three inputs: CLOCK, RESET, and CLOCK INHIBIT signal. The CLOCK input circuit employs Schmitt trigger action, providing pulse shaping that allows unlimited clock input pulse rise and fall times.

The counters are advanced one count at a positive clock signal transition and a low CLOCK INHIBIT signal. Counter advancement is inhibited when the CLOCK INHIBIT signal is high. A high RESET signal clears the counter to its zero count. These circuits utilize the Johnson counter configuration, enabling high-speed operation, 2-input decode-gating, and spike-free decoded outputs. Anti-lock gating ensures proper counting sequence. The decoded outputs remain low and only go high during their respective decoded time slot. Each decoded output stays high for one full clock cycle. Additionally, a CARRY-OUT signal completes one cycle every 10 clock input cycles in CD4017B or every 8 clock input cycles in CD4022B. It's used to ripple-clock the subsequent device in a multi-device counting chain.

Both CD4017B and CD4022B are available in various package options, including 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes). CD4017B types are also supplied in 16-lead small-outline packages (M and M96 suffixes).
