Claim 7:
8. An electronic device, comprising:
a semiconductor substrate;
a bidirectional transistor switch formed on the substrate and including a first source node, a second source node and a common drain node;
a first transistor formed on the substrate and including a first source terminal, a first drain terminal and a first gate terminal, the first source terminal connected to the substrate, the first drain terminal connected to the first source node and the first gate terminal connected to the second source node;
a second transistor formed on the substrate and including a second source terminal, a second drain terminal and a second gate terminal, wherein the second transistor is arranged to couple the second source terminal to the semiconductor substrate in response to a voltage of the first source node at a voltage that is higher than a voltage of the semiconductor substrate;
a third transistor formed on the substrate and including a third drain, a third source and a third gate, the third gate connected to a voltage source, the third drain connected to the first source node and the third source connected to the second gate terminal; and
a fourth transistor formed on the substrate and including a fourth drain, a fourth source and a fourth gate, the fourth gate connected to the voltage source, the fourth drain connected to the second source node, and the fourth source connected to the first gate terminal.
