Abstract
Embodiments of an integrated circuit driver, a method for operating integrated circuit driver, and predrivers are described. In one embodiment of the integrated circuit driver, a bias control circuit provides a bias signal for a first mode and a second mode. The bias signal has a first voltage level associated with operation in the first mode and a second voltage level associated with operation in the second mode. An output driver circuit receives the bias signal. In the first mode, the output driver circuit operates as a supply referenced driver, and in the second mode, the output driver circuit operates as a ground referenced driver.
