Abstract:
An input/output (I/O) mixed-voltage drive circuit and electrostatic discharge protection device for coupling to an I/O pad. The device includes an NFET device having a gate, a drain, a source and body, the gate adapted for coupling to a pre-drive circuit, the source and the body being coupled to one another and to ground. The device also includes a bipolar junction transistor having a collector, an emitter and a base, the emitter being coupled to the drain of the NFET and the collector being coupled to the I/O pad.
