ABSTRACT:
An ESD protection circuit and structure for integrated circuit devices uses a lateral NPN transistor to provide a low resistance discharge path for ESD transient voltages. A preferred structure also includes a modification to an N-channel output drive transistor to eliminate the parasitic bipolar transistor that induces snapback.
