DESCRIPTION

The HCF4026B is a monolithic integrated circuit

fabricated in Metal Oxide Semiconductor

technology available in DIP and SOP packages.

The HCF4026B consists of a 5-stages 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. This device is particularly

advantageous in display applications where low

power dissipation and/or low package count are

PIN CONNECTION

important. This device has CLOCK, RESET,

CLOCK INHIBIT, DISPLAY ENABLE input and

CARRY OUT, DISPLAY ENABLE, UNGATED "C"

SEGMENT and 7 DECODED outputs (a to g).

A high RESET signal clears the decade counter to

its zero count. The counter is advanced one count

at the positive clock signal transition if the CLOCK

INHIBIT signal is low. Counter advancement via

the clock line is inhibited when the CLOCK

INHIBIT signal is high. Antilock gating is provided

on the JOHNSON counter, thus assuring proper

counting sequence. The CARRY-OUT (C

OUT

)

signal completes one cycle every ten CLOCK

INPUT cycles and is used to clock the succeeding

decade directly in a multi-decade counting chain.
