Abstract
An apparatus comprising a device and a resistor. The device generally comprises (i) a gate configured to receive an input voltage, (ii) a drain coupled to a first supply voltage, and (iii) a source coupled to an output. The resistive element is generally coupled between the source and a second supply voltage. The apparatus generally provides voltage tolerance between the input voltage and the output.
