DESCRIPTION

The HCF4017B is 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. 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 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 10 clock input

cycles and is used to ripple-clock the succeeding

device in a multi-device counting chain.
