Octal Counter
The MC14022B 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 applications as well as octal counter
or octal decode display applications.
• Fully Static Operation
