摘要：
An object of the present invention is to realize reduction in an area of an output stage driver in an interface circuit that switches between two transmission systems. The interface circuit has two driver circuits and a drive control circuit that can switch between two driving systems that are a voltage driving system and a current driving system. The two driver circuits are connected to a power supply potential via the drive control circuit. Two input signals and inverted logic signals of the input signals are inputted via a selection circuit. According to a control signal inputted into the drive control circuit, the interface circuit switches between the voltage-driving type single-ended transmission system and current driving type differential transmission system.
