Disclosed is a differential pre-emphasis driver. The driver includes a first current source supplying a first current, a second current source supplying a second current greater than the first current, a first select circuit for selectively connecting the first current source to a first output terminal or a second output terminal, and a second select circuit for selectively connecting the second current source to the first output terminal or the second output terminal. The first and second select circuits pre-emphasize a transmission signal by selectively combining the first output terminal, the second output terminal, the first current source and the second current source.
