ABSTRACT:
A plurality of output transistors for an output buffer of a semiconductor device are provided in parallel. Potentials to be applied to gates of output transistors are set to different levels upon conduction of the output transistors. By sequentially rendering the transistors conductive in the order of increasing voltage during conduction, rapid flow of a large amount of current is prevented, thereby reducing ringing. More preferably, the transistors are increased in size according to the order of conduction of the output transistors.
