Abstract: An integrated circuit includes a differential signal driver that receives a first signal from a first input terminal, receives a second signal, which is a differential signal of the first signal, from a second input terminal, outputs a first output signal corresponding to the first signal to a first output terminal, and outputs a second output signal corresponding to the second signal to a second output terminal. The integrated circuit further includes a first capacitor unit connected to the first output terminal and controlling a slew rate of the first output signal based on a first capacitance, a second capacitor unit connected to the second output terminal and controlling a slew rate of the second output signal based on a second capacitance, and a phase selection unit that receives the first signal and provides the first signal to the second capacitor unit, and that receives the second signal and provides the second signal to the first capacitor unit, so as to control the slew rates of the first and second output signals.
