  • Self-reset flip-flop with self shut-off mechanism
    Patent number: 6188259
    Abstract: An electronic system is described for a flip-flop circuit having a data input stage with a clock input and a data input, coupled to an output stage which generates at least one data output, a reset circuit coupled to said data output stage for resetting the logic state of the data outputs to a predetermined desired condition, and a shutoff circuit coupled to said data input stage blocking data input from being acted on by said data input stage. An alternate embodiment includes a data processing circuit with a feedback mechanism coupled with the reset circuit of the flip-flop which informs the flip-flop that data is no longer required.
