Abstract: A switch device including a switch circuit and switch controller. The switch circuit comprises first and second switches to selectively enable a path between an input terminal and an output terminal. The switch controller refers to a selection signal and a switch signal to respectively generate a first switch control signal at a first switch control signal output terminal and a second switch control signal at a second switch control signal output terminal. When the voltage level of an input signal at the input terminal is larger than a power voltage, the switch controller generates the first switch control signal and the second switch control signal capable of turning off the switch circuit. When the voltage level of the input signal is not larger than the power voltage, the switch controller generates the first switch control signal and the second switch control signal according to the switch signal.
