A bus driver reduces a ringing produced in the output waveform thereof. In the output waveform traveling over a bus, the ringing is produced due to reflections of the output waveform at a plurality of LSI packages. In the bus driver, at least one diode is connected between a transistor for driving a signal and a power supply source. The diode of the bus driver clamps waveform components having a potential higher than a predetermined threshold on the bus and reduces ringings of the bus driver output waveform.
