| Zusammenfassung: | An interface circuit according to one aspect of the present invention may include a receiving circuit operating on a supply voltage lower than a high-level voltage value of an input binary signal, an input level determination circuit generating an input level determination signal having a frequency higher than a frequency of the binary signal and controls whether to output the input level determination signal or not, based on a voltage level of the binary signal, and an AC coupling element connected between an output terminal of the input level determination circuit and an input terminal of the receiving circuit. |
