Product Overview

CD4022B is 4-stage Johnson counters with 8 decoded output. Inputs comprise a CLOCK, a RESET, and also a CLOCK INHIBIT signal. Schmitt trigger action from the CLOCK input circuit offers pulse shaping which enables infinite clock input pulse rise and fall times. These counters are advanced one count in the favorable clock signal transition in the event the CLOCK INHIBIT signal is reduced. Counter advancement through the clock line is inhibited while the CLOCK INHIBIT signal is large. A top RESET signal avoids the counter to its own zero counts. Anti-lock gating is supplied, thus assuring appropriate counting sequence. The decoded output signal is generally low and goes high in their various decoded slot. Each decoded output stays high for one complete clock cycle.
