Abstract
A pass gate multiplexer receiver integrated circuit on a semiconductor substrate including a pass gate circuit including first and second field effect transistors of opposite polarity for providing an input signal to an output line, the first transistor including a first bipolar transistor for providing clamping an electrostatic discharge protection and the second transistor including a second bipolar transistor for providing clamping and electrostatic discharge protection. A control circuit is connected to the pass gate to control operation. In a second embodiment the pass gate further includes a clamping circuit to provide further clamping and electrostatic discharge protection.
