According to one embodiment, an output driver which outputs an output signal to a transmission line, the output driver includes a pre-driver and a main driver. The pre-driver changes the duty ratio of a first drive signal and the duty ratio of a second drive signal to a plurality of patterns in accordance with a control signal. The main driver connects in series a first driver driven by the first drive signal and a second driver driven by the second drive signal. The main driver outputs the output signal to the transmission line from a connection node of the first and second drivers. |
