| description | The present invention relates generally to integrated circuits, and in particular to electrostatic discharge (ESD) protection of circuitry coupled to an input stage of an integrated circuit.
An integrated circuit is disclosed in which a steering diode is coupled between an input bond pad and a ground bond pad. The steering diode is reverse biased when a voltage applied to the input bond pad exceeds the voltage at the ground bond pad. A circuit coupled between the input bond pad and the ground bond pad includes a transistor having a first electrode coupled the input bond pad and a second electrode coupled to the ground bond pad. There may be other circuit elements between the emitter and the ground bond pad. At least two series coupled diodes are coupled between the input bond pad and the ground bond pad. The at least two series coupled diodes provide ESD protection to the transistor and circuit coupled between the input bond pad and the ground bond pad. |
