Abstract
A device comprises, a first power source providing a first voltage, a second power source providing a second voltage less than the first voltage, a first bias voltage source providing a first bias voltage between the first voltage and the second voltage, a second bias voltage source providing a second bias voltage between the first voltage and the second voltage, the second bias voltage greater than or equal to the first bias voltage. The device also includes an output, a pull up network coupled in series between the first power source and the output pad including: a first gate coupled to the bias voltage source; and a second gate coupled to a signal that varies between first bias voltage and first power source. The device includes and a pull down network coupled between the output pad and second power source and including: a third gate coupled to the second bias voltage source; and a fourth gate coupled to a signal that varies between the second power source and the second bias voltage source.
