Claim Text:
1. An apparatus to switch signals, the apparatus comprising: a reference node to receive a reference voltage; a first node to provide a signal; and a circuit including a second node to receive different voltages greater than the reference voltage and to cause the signal at the first node to switch between a first voltage greater than the reference voltage and a second voltage greater than the reference voltage, wherein the circuit includes a transistor having a gate coupled to the second node, the transistor having a voltage tolerance less than a supply voltage of the circuit, a first additional transistor coupled between the gate of the transistor and a supply node, a second additional transistor coupled between the gate of the transistor and the supply node, and a third additional transistor coupled between the transistor and the reference node, the third additional transistor including a gate coupled to the supply node.
