Claim 14:
15. The output circuit according to claim 14, wherein the level adjustment circuit comprises:
a first level shift circuit, adjusting a level of the digital signal to generate a first signal;
a second level shift circuit, adjusting the level of the digital signal to generate a second signal;
a first transistor, receiving the first supply voltage, and selectively turned on according to the first signal;
a second transistor, biased by the second voltage, wherein a first terminal of the second transistor is coupled to the first transistor;
a third transistor, coupled between the second transistor and an output node, and turned on by the first bias voltage, wherein the output node outputs the digital output signal;
a fourth transistor, coupled between the output node and a fifth transistor, and turned on by the second bias voltage;
the fifth transistor, biased by the first voltage; and
a sixth transistor, coupled between the fifth transistor and a ground, and selectively turned on according to the second signal.
