HD74HC4022

Octal Counters/Dividers

Description

The HD74HC4022 is a four-stage Johson octal counter with built-in code converter. High speed operation

and spike-free outputs are obtained by use of a Johson octal counter design. The eight decoded outputs are

normally low, and go high only at their appropriate octal time period. The output changes occur on the

positive-going edge of the clock pulse. This part can be used in frequency division application as well as

octal counter or octal decode display applications.
