Abstract
A high voltage tolerant differential receiver circuit includes a voltage divider ladder that is operative to divide in half differential input signals that are greater than threshold voltages of the voltage divider ladder. A pass gate circuit is operative to receive differential input signals that are below the threshold voltage of the voltage divider ladder. Outputs from the voltage divider ladder and the pass gate circuit are provided to separate comparators. Output from the comparators are combined to generate a signal in the voltage domain of receiver circuitry.
