ABSTRACT:
An interface circuit includes first transistors for driving bus lines through which data is transmitted between a plurality of semiconductor elements. The interface circuit controls the data transmitted through the bus lines when the first transistors are in the ON state. The interface circuit also includes second transistors which share a ground line with the first transistors and in which currents equivalent to currents flowing in the first transistors flow in the ON state. The second transistors are set in the ON state when the first transistors are set in the OFF state, and vice versa.
