ABSTRACT:
An output buffer circuit includes a control unit and an output driver. The control unit generates a control signal in response to a mode signal applied from an internal circuit. The output driver selectively performs a driver operation, a termination operation or an electrostatic discharge (ESD) protection operation in response to the control signal.
