DESCRIPTION
The HCC4017B/4022B (extended temperature
range) and HCF4017B/4022B (intermediate tem-
perature range) are monolithic integrated circuits,
available in 16-lead dual in-line plastic or ceramic
package and plastic micro package.
The HCC/HCF4017B and HCC/HCF4022B are 5-
stage and 4-stage Johnson counters having 10 and
8 decoded outputs, respectively. Inputs include a
CLOCK, a RESET, and a CLOCK INHIBIT signal.
Schmitt trigger action in the CLOCK input circuit pro-
vides pulse shaping that allows unlimited clock input
pulse rise and fall times. These counters are ad-
vanced one count at the positive clock signal tran-
sition if the CLOCK INHIBIT signal is low. Counter
advancement 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 gat-
ing, and spike-free decoded outputs. Anti-lock gat-
ing 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
