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 apparatusis provided with receiving comparatorwhich has first signal lineand second signal linefor differential input; NOR circuitthat 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 circuitthat retrieves, by means of a trigger signal from NOR circuit, and holds an output RCV of receiving comparator; wherein selection circuitselects the output of receiving comparator, when the first signal of first signal lineand the second signal of second signal lineare 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.
