Abstract
A circuit includes a first comparator block configured to output a voltage equal to a higher of a supply voltage and a bias voltage, a second comparator block configured to output a voltage equal to a higher of the bias voltage and an external voltage supplied through an Input/Output (IO) pad, and a third comparator block configured to output a voltage equal to a higher of the output of the first comparator block and the output of the second comparator block. A voltage across one or more constituent active element(s) of each of the first comparator block, the second comparator block, and the third comparator block is within an upper tolerable limit thereof during each of a normal operation, a failsafe operation, and a tolerant operation.
