Abstract
A bus driving device is provided with a driver circuit for driving a bus line thereof. The driver circuit includes an MOS transistor whose well is separated from other circuits. Further, the bus driving device is provided with a voltage control section for adjusting a well voltage, in accordance with a level of a signal in the bus line. With this bus driving device, a threshold voltage of the MOS transistor is set at a predetermined target value.
