Methods and systems are described for an output driver composed of complementary metal-oxide semiconductor (CMOS) devices, the output driver having a line driver control stage configured to selectively output a reference voltage or a first supply voltage at the control stage output node in response to a data signal, and a line driver output circuit configured to generate an output signal on a multi-wire bus, wherein the CMOS devices of the line driver output circuit are calibrated to have an on-resistance matched to a termination impedance via first and second supply voltages provided to the line driver control stage and the line driver output circuit, respectively.
