Abstract: A differential signal transmitter circuit includes an output driver circuit and a leakage current preventing circuit. The output driver circuit is configured to transmit a pair of differential signals according to a supply power. The leakage current preventing circuit is coupled to the supply power and configured to couple the supply power to the output driver circuit in a power on state and decouple the supply power from the output driver circuit in a power off state.
