Claim 0:
1. An optocoupler circuit comprising:
a first direction path configured to transmit signals from a first terminal to a second terminal; and
a second direction path configured to transmit signals from the second terminal to the first terminal;
wherein the first direction path comprises:
a first level shifter configured to receive a first input signal at the first terminal, and shift a voltage level of the first input signal to a first shifted voltage level with respect to a first ground level in a first power domain, to provide a first shifted signal;
a first optocoupler configured to receive the first shifted signal, and generate a first optocoupler signal in response to the first shifted signal; and
a second level shifter configured to receive the first optocoupler signal, and shift a voltage level of the first optocoupler signal to a second shifted voltage level with respect to a second ground level in a second power domain, to provide a second shifted signal at the second terminal.
