A data receiving apparatus which makes it possible to obtain reliable received data during EOP period and a preceding period, and which makes it possible to receive serial data in a reliable manner. Data receiving apparatus 100 is provided with receiving comparator 102 which has first signal line 101a and second signal line 101b for differential input; NOR circuit 105 that outputs a logical output, as a trigger signal, at the time the first signal and the second signal have changed from out-of-phase to in-phase; and D-FF circuit 107 that retrieves, by means of a trigger signal from NOR circuit 105, and holds an output RCV of receiving comparator 102; wherein selection circuit 108 selects the output of receiving comparator 102, when the first signal of first signal line 101a and the second signal of second signal line 101b are out-of-phase with each other, and outputs, as received data, a value held in D-FF circuit, when the first signal and the second signal have changed from out-of-phase to in-phase.
