Abstract
An input circuit includes a first buffer having a first power terminal coupled to a first supply voltage, a second power terminal coupled to ground potential, an input to receive an input signal, and an output to generate a first output signal, a second buffer having a first terminal coupled to a second supply voltage, a second terminal coupled to a bias node, an input to receive the input signal, and an output to generate a second output signal, and a control circuit configured to selectively connect the bias node either to the second supply voltage or to ground potential in response to an enable signal.
