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.
The MC14022B is a four‑stage Johnson octal counter with built‑in code converter. It provides eight decoded outputs that are normally low and go high on the appropriate octal time period, with outputs changing on the positive‑going edge of the clock pulse. The device can be used for frequency‑division, octal counting, or octal decode display applications and is a pin‑for‑pin replacement for the CD4022B.
