DESCRIPTION
The HCF4022B is a m onolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
The 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

when the CLOCK I NHIBIT signal is high. A high
RESET signal clears the counter to it s ze r o co unt.
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 p roper
counting sequence. The decoded outputs are
normally low and go high only at their respective
decoded time slot. Eac h decoded ou tput 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.
