Claim Text:
1. An integrated circuit, comprising: an input-output circuit having an input node that is coupled to an input-output pad via a resistor; first and second power clamp circuits; first and second power rails and a ground power rail, wherein the first power clamp circuit is coupled between the first power rail and the ground power rail, and wherein the second power clamp circuit is coupled between the second power rail and the ground power rail; a first electrostatic discharge (ESD) diode connected between the input-output pad and the first power rail; a second electrostatic discharge (ESD) diode connected between the input-output pad and the ground power rail; a third electrostatic discharge (ESD) diode connected between the input node and the second power rail; and a fourth electrostatic discharge (ESD) diode connected between the input node and the ground power rail.
