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.
