  • Patent number: 6072342
    Abstract: A circuit for driving GTL-type buses actively drives a bus trace towards a first reference voltage when a signal in a first voltage state is detected at its input and actively drives the bus trace towards a second reference voltage for a selected period when the signal at its input transitions from the first voltage state to a second voltage state. The circuit includes a flip-flop for storing the sequential voltage states of the signal, logic for comparing the current voltage state of the signal with a replica of the preceding voltage state of the signal, and first and second transistors of complementary conductivity types, for driving the bus trace to first or second reference voltages, respectively, when activated. The first transistor is turned on when the signal is in the first voltage state.
