Tristable output buffer with state transition control

Abstract: Voltage on a circuit ground terminal in an output buffer is controlled by limiting induced voltage on a circuit ground pad as the output makes a transition from a high voltage level to a low voltage level thereby minimizing deleterious effects on other circuits connected to the common circuit ground terminal. A ground bounce circuit controls the bias on a transistor connecting the output to the circuit ground terminal with power saver circuitry limiting actuation of the ground bounce circuitry except during the high to low transitional phase.
