ABSTRACT:
A level shifter for an integrated circuit. In one embodiment, the level shifter is a bi-directional level shifter with a signal terminal located in each voltage domain that can be utilized as input or output terminal. In some embodiments, the level shifter includes transistors for cutting off the flow of current between domain power supplies when the input terminals are at a particular state. In one embodiment, only one signal line of the level shifter crosses a domain boundary.
