Abstract: A level shifting circuit operates at a high voltage level without stressing the transistors. The circuit has the ability to swing between large supply domains. Multiple output voltage levels are supported for the level shifted signal. Additionally, output nodes are stably driven to supply voltage levels that do not vary with respect to process corner and temperature.
