Summary:An input signal detecting circuit includes a plurality of comparators configured to output a plurality of differential output signals in response to a differential input signal, respectively; and a differential exclusive OR circuit configured to output an exclusive OR resultant signal from the plurality of differential output signals outputted from the plurality of comparators. In at least one of the plurality of comparators, a DC operation voltage is changed in response to a control signal supplied to the comparator.
