Description
The HD74HC4022 is a four-stage Johnson octal counter with built-in code converter. High speed operation and spike-
free outputs are obtained by use of a Johnson 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.
