Abstract
A level shifting output circuit converts a signal from a core voltage to an I/O voltage without causing voltage overstress on transistor terminals in the level shifting output circuit. The output circuit includes protection transistors to protect various transistors in the output circuit from overvoltage conditions including those transistors coupled to I/O power supply nodes.
