An analog multiplexer may be used for sampling an input voltage that is capable of having a higher voltage level than an upper supply voltage. The analog multiplexer includes a plurality of input switch circuits and a shorting switch circuit. The plurality of input switch circuits include n-type or p-type laterally diffused field effect transistors (NLDFETs or PLDFETs). At least one of the input switch circuits includes a level shifting switch circuit that is able to sample an input voltage that is greater than the upper supply voltage for the multiplexer. A shorting switch circuit, at an output of the multiplexer, includes a capacitively coupled gate drive circuit and is configured to short a first differential output to a second differential output after the input voltage is sampled.
