Claim 6:
7. The optocoupler circuit of claim 1, wherein the second direction path comprises:
a third level shifter configured to receive a second input signal at the second terminal, and shift a voltage level of the second input signal to a third shifted voltage level with respect to the second ground level in the second power domain, to provide a third shifted signal;
a second optocoupler configured to receive the third shifted signal, and generate a second optocoupler signal in response to the third shifted signal; and
a fourth level shifter configured to receive the second optocoupler signal, and shift a voltage level of the second optocoupler signal to a fourth shifted voltage level with respect to the first ground level in the first power domain, to provide a fourth shifted signal at the first terminal.
