<p>A relay circuit for relaying signal transmission between a first circuit that is driven by a first voltage and a second circuit that is driven by a second voltage different from the first voltage, the relay circuit being arranged between the first circuit and the second circuit, the relay circuit includes: a waveform shaping circuit that obtains a shaped voltage by shaping a waveform of the second voltage in order to make a change of the second voltage steeper; and a buffer circuit that is driven by the first voltage and interrupts a signal transmission by the buffer circuit if the shaped voltage obtained by the waveform shaping circuit falls to or below a predetermined value, the shaped voltage being input to the buffer circuit as a control signal.</p> |
