Abstract: A method and integrated circuit renders a shunt structure non-conductive during a power up event or noise event for and in addition, during an electrostatic discharge event, keeps the shunt structure conductive for a period of time to discharge electrostatic energy through the shunt structure. In one example, a shunt structure, such as a transistor, is interposed between a power node and a ground node. Circuitry is operative during a power up event or noise event, to render the shunt structure non-conductive for a period of time during the power up event or during the noise event (when power is applied). Second circuit is operative, during an electrostatic discharge event, to keep the shunt structure conductive for a period of time to discharge electrostatic energy through the shunt structure. In one example, a plurality of resistor/capacitors (RC) circuits are utilized wherein the RC circuits have different time constants.
