Claim 5:
6. The optocoupler circuit of claim 5, wherein the first output circuit comprises:
a first resistor and a second resistor series connected between a voltage supply having a second terminal voltage level and a ground having the second ground level in the second power domain, wherein a first node between the first resistor and the second resistor receives the second shifted signal from the second level shifter; and
a first transistor having a control terminal connected to the first node between the first resistor and the second resistor, a first current terminal connected to the ground, and a second current terminal connected to the voltage supply having the second terminal voltage level by way of a third resistor and a fourth resistor, wherein a second node between the third resistor and the fourth resistor is connected to the second terminal.
