Abstract

PURPOSE:To produce the strobe signal at the reception side, by using the timing signal which is reversed with every transfer of the data as the synchronous signal for transfer of the data and then utilizing the level inversion of the timing signal. CONSTITUTION:The data D0-Dn-1 are transmitted via the output buffer circuits OB1-OBn-1. At the same time, the timing signal Dn generated from the synchronous timing generating circuit 2 is transmitted via the output buffer circuit OBn. And the pulse generating circuit 4 is provided to the output of the input buffer circuit IBn received the signal Dn. At the circuit 4, the strobe pulse phi is produced by means of the level inversion of the signal Dn and then supplied to the latch circuit 5. Then the data D1-Dn-1 supplied in parallel are taken in by the circuit 5 with the pulse phi used as the set pulse.
