Claim 5:
6. The level shifter as claimed in claim 4, wherein:
the first protection circuit further has a first multiplexer, coupling the second voltage to the gate terminal of the second transistor in response to the high-level state of the input signal, and coupling the drain terminal of the second transistor to the gate terminal of the second transistor in response to the low-level state of the input signal; and
the second protection circuit further has a second multiplexer, coupling the second voltage to the gate terminal of the fourth transistor in response to the low-level state of the input signal, and coupling the drain terminal of the fourth transistor to the gate terminal of the fourth transistor in response to the high-level state of the input signal.
