Abstract
A bus interface circuit includes a precharge circuit including a switch element which is inserted between a bus line and a precharge power supply, receives a precharge control signal PE at its control terminal, and is turned on when the precharge control signal is active. The precharge circuit precharges the bus line to a predetermined precharge voltage from the precharge power supply via the switch element that is turned on. The precharge voltage is a predetermined voltage between a high-potential power supply voltage VDD and a low-potential power supply voltage VSS. When a signal received by an output circuit for output to the bus line has a first logic value, an output circuit sets the bus line, which has been precharged to the precharge voltage, from the precharge voltage to the predetermined VSS.
