<p>PROBLEM TO BE SOLVED: To prevent the generation of radiation noises from signal lines and the occurrence of a crosstalk between signals concerning a data transfer device for transferring data through the plural signal lines. SOLUTION: Corresponding to a random number generated by a random number generating circuit 17, a selector 20 selects any one of delay clocks 0-3 and outputs an output clock, with which the timing of rising and falling is changed at random, from an output terminal 20f. Timing to switch data to be respectively outputted from flip-flops 10-12 is changed at random as well.</p> |
