ABSTRACT:
The present invention is a driver circuit for interfacing electronic components which have different supply voltages. The driver circuit includes a source terminal for receiving a source voltage, an output terminal connected to an off-chip electronic component, and a pull up circuit disposed between the source and output terminals for providing a field effect controlled current path between the source terminal and the output terminal. The pull up circuit includes a first transistor in series with a second transistor, the second transistor providing overvoltage stress relief for the first transistor.
