DESCRIPTIO N
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-stageJohnson counters having 10and
8 decoded outputs, respectively. Inputs include a
CLOCK, a RESET, and a CLOCK INHIBIT signal.
SchmitttriggeractionintheCLOCKinputcircuit providespulse shapingthatallowsunlimitedclockinput
pulse rise and fall times. These counters are advanced one count at the positive clock signal transition if the CLOCK INHIBIT signal is low. Counter

CLOCKINHIBITsignalishigh. AhighRESETsignal
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

Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device
reliability.
