Available. The Philips HEF4022B is a 4-stage divide-by-8 Johnson counter, designed for digital counting applications. It features eight decoded active HIGH outputs (O0 to O7) and an active LOW output from the most significant flip-flop (O4-7). The device is equipped with active HIGH and active LOW clock inputs (CP0, CP1) and an overriding asynchronous master reset input (MR). The counter advances on specific clock transitions, as detailed in the function table. This component is suitable for use in various digital systems requiring precise counting and timing functions.
