Claim 8:
9. The level shifter as claimed in claim 8, wherein:
the first protection circuit further has a third multiplexer, coupling the fourth voltage to the gate terminal of the sixth transistor in response to the low-level state of the input signal, and coupling the drain terminal of the sixth transistor to the gate terminal of the sixth transistor in response to the high-level state of the input signal; and
the second protection circuit further has a fourth multiplexer, coupling the fourth voltage to the gate terminal of the eighth transistor in response to the high-level state of the input signal, and coupling the drain terminal of the eighth transistor to the gate terminal of the eighth transistor in response to the low-level state of the input signal.
