An audio I/O system and method for a guitar equipped with a USB interface is disclosed. The audio I/O system converts an analog audio signal generated from an electronic guitar into a digital audio signal using a USB guitar module of the electronic guitar, performs signal processing on the digital audio signal according to the USB standard, transmits the signal-processed resultant signal to a Personal Computer (PC), employs a variety of application programs stored in the PC, and outputs the corresponding audio signal via a speaker of the PC. The audio I/O system receives the mixed/edited signal from the PC, performs signal processing on the received signal, outputs the corresponding signal via the headphone or speaker, allows the PC to output pre-stored audio signals of other guitars, plays the electronic guitar, and stores the played signal in the PC in real time.

An output buffer includes an output terminal, a pull up module, a pull down module and an output latching module. The pull up module pulls up the output terminal to a first source voltage when the pull up module is active The pull down module pulls down the output terminal to a second source voltage when the pull down module is active. The output latching module latches a data signal in response to a state of an output clock signal in a first operation mode. The output latching module latches the data signal in response to a leading edge of the output clock signal in a second operation mode. The output latching module drives the pull up module and the pull down module in response to the data signal latched by the output latching module, so that the output latching module outputs the data signal to the output terminal in a second operation mode.
