ABSTRACT:
An input circuit for an integrated circuit includes an electrostatic discharge circuit. The input circuit incorporates an interconnect pad, an ESD protection resistor, and an interconnect line that are coupled to the active internal components of the integrated circuit. The interconnect pad is coupled to the interconnect line, and the interconnect line is coupled to the ESD protection resistor which is coupled to the active internal components of the integrated circuit. The ESD protection resistor is positioned physically proximate to the active internal components of the integrated circuit and adjusted in value to compensate for the intrinsic resistance or RC time constant of the interconnect line. The circuitry provides for a lower signal propagation delay through the external connection because of lower RC time constants to drive the capacitance of the interconnect.
