The HCC4026B/4033B (extended temperature

range) and HCF4026B/4033B (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/HCF4026B and HCC/HCF4033B each con-

sist of a 5-stage Johnson decade counter and an

output decoder which converts the Johnson code to

a 7-segment decoded output for driving one stage

in a numerical display. These devices are particu-

larly advantageous in display applications where

low power dissipation and/or low package count are

important. Inputs common to both types are

CLOCK, RESET, & CLOCK INHIBIT ; common out-

puts are CARRY OUT and the seven decoded out-

puts (a, b, c, d, e, f, g). Additional inputs and outputs

for the HCC/HCF4026B include DISPLAY ENABLE

input and DISPLAY ENABLE and UNGATED ”C-

SEGMENT” outputs. Signals peculiar to the

HCC/HCF4033B are RIPPLE-BLANKING INPUT

AND LAMP TEST INPUT and a RIPPLE-BLANK-

ING OUTPUT. A high RESET signal clears the de-
