Abstract
A precharge transistor precharges a bus. A discharge transistor discharges the bus. A push-pull driver is connected to the bus, and consists of a p-channel MOS transistor and an n-channel MOS transistor. The push-pull driver sets the potential of the bus to 'H' level or 'L' level. A detection circuit detects which one of the discharge transistor and the push-pull driver is being driven. When the push-pull drive is being driven, a control circuit renders the precharge transistor inoperative.
