Claim 11:
12. The optocoupler circuit of claim 11, wherein the second output circuit comprises:
a fifth resistor and a sixth resistor series connected between a voltage supply having a first terminal voltage level and a ground having the first ground level in the first power domain, wherein a third node between the fifth resistor and the sixth resistor receives the fourth shifted signal from the fourth level shifter; and
a second transistor having a control terminal connected to the third node between the fifth resistor and the sixth resistor, a third current terminal connected to the ground, and a fourth current terminal connected to the voltage supply having the first terminal voltage level by way of a seventh resistor and an eighth resistor, wherein a fourth node between the seventh resistor and the eighth resistor is connected to the first terminal.
