Abstract: An interface circuit includes a phase inverter. An input end of the phase inverter is connected to a signal output end of a first power domain circuit, and an output end of the phase inverter is connected to a signal input end of a second power domain circuit. A power end of the phase inverter is connected to a power supply of the first power domain circuit, and a ground end of the phase inverter is connected to a reference ground of the second power domain circuit. Alternatively, a power end of the phase inverter is connected to a power supply of the second power domain circuit, and a ground end of the phase inverter is connected to a reference ground of the first power domain circuit.
