ABSTRACT:
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 apparatus100is provided with receiving comparator102which has first signal line101aand second signal line101bfor differential input; NOR circuit105that 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 circuit107that retrieves, by means of a trigger signal from NOR circuit105, and holds an output RCV of receiving comparator102; wherein selection circuit108selects the output of receiving comparator102, when the first signal of first signal line101aand the second signal of second signal line101bare 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.
