  • Multifunction flip-flop-type circuit
    Patent number: 4864161
    Abstract: A flip-flop-type circuit capable of operating either as a conventional D flip-flop or as a device which merely passes through the data applied to it (so-called "flow-through mode"). In the flow-through mode, the circuit has the additional capability of being able to latch in the data flowing through it at any time. Thus the circuit can also operate as a level-sensitive latch.
