ABSTRACT:
Systems and methods are disclosed herein to provide improved I/O techniques. For example, in accordance with an embodiment of the present invention, an integrated circuit includes a reference circuit adapted to receive a first reference signal and provide a second plurality of reference signals based on the first reference signal, with the reference circuit providing default voltage levels for the second plurality of reference signals if a first control signal is asserted. An input/output circuit, coupled to the reference circuit and to an output driver, receives the second plurality of reference signals to control the output driver to provide an output signal, with the output driver operated with the default voltage levels if the first control signal is asserted.
