1. A device comprising:

  • a circuit operable to assist a transition of a signal on a wire and to drive said signal after said transition, said circuit assisting said transition and driving said signal with said circuit operating within a first voltage range, said circuit being reset for a subsequent transition with said circuit operating within a second voltage range, wherein said first and second voltage ranges are separated by a gap that provides a margin between said first and second voltage ranges;

    wherein said circuit comprises;

    a rising transition subcircuit that operates in a range above a first threshold voltage; and

    a falling transition subcircuit coupled to said rising transition circuit and that operates in a range below a second threshold voltage, wherein said first and second threshold voltages are separated by a gap that provides a margin between said first and second threshold voltages.
