A source driver of a display apparatus includes a receiving controller receiving a first status information signal and outputting a second status information signal and a receiving circuit receiving a transmission signal in response to the second status information signal and recovering the transmission signal to receiving data. The receiving controller includes a transition detection circuit detecting a transition of the first status information signal and outputting a transition detection signal, a delay circuit delaying the transition detection signal by a predetermined time and outputting a delay detection signal, and an output circuit receiving the first status information signal and outputting the second status information signal in response to the delay detection signal.
