An integrated circuit for level-shifting voltage signals comprising an input/output pad, and an input/output circuit coupled to the output pad having a plurality of devices operating with a bias supply voltage operable to shift between the range of the bias supply voltage to the range of an input/output supply voltage that is higher than the bias supply voltage is provided. In addition, an integrated circuit comprises an input circuit coupled to an input pad operable to input shift signals from an input/output supply voltage range to a core supply voltage range, an output circuit coupled to an output pad operable to shift output signals from a bias supply voltage range to an input/output supply voltage range, and a core circuit coupled to the input and output circuits and having a gate dielectric thickness substantially similar to a gate dielectric thickness of the input circuit and the output circuit.
