In an output driver circuit, a replica circuit includes seventh and eighth transistors corresponding to first and second transistors, respectively, ninth and tenth transistors corresponding to third or fifth, and fourth or sixth transistors in a driver circuit, respectively, and a resistor corresponding to a termination resistor. A reference voltage and a voltage of a node between the ninth transistor and the resistor are input to an operational amplifier, and an output signal of the operational amplifier is input to gates of the first and seventh transistors.
