Abstract
Systems and methods are disclosed, including a protection multiplexer circuit configured to receive a control signal and a reference voltage, to provide the reference voltage at an output when the control signal is in a first state, and to isolate the reference voltage from the output when the control signal is in a second state. The protection multiplexer circuit includes cascaded first and second transistors, wherein the first transistor is a native transistor. Control inputs of the first and second transistors are configured to receive the control signal, a first terminal of the first transistor is configured to receive the reference voltage, and the first terminal of the second transistor is coupled to the output. Methods of operation are disclosed, and other embodiments.
