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.
