Abstract:
1. A circuit for assisting signal transitions on a wire, said circuit comprising: first circuitry coupled to said wire, said first circuitry causing a first transistor to turn on in response to a rising transition of a signal on said wire and then turn off after a first period of time, said first transistor driving the output of said circuit to a high state to assist in said rising transition; second circuitry coupled to said wire, said second circuitry causing a second transistor to turn on in response to a falling transition of a signal on said wire and then turn off after a second period of time, said second transistor driving said output to a low state to assist in said falling transition; and third circuitry coupled to said wire, said third circuitry for maintaining said high state at said output from said rising transition until said falling transition after said first transistor turns off, said third circuitry also for maintaining said low state from said falling transition until a next rising transition after said second transistor turns off.
