PURPOSE:To make work easy by making the number of wires between a transmitting and a receiving circuits less than the number of data to be transmitted. CONSTITUTION:When a transmission command signal is supplied, a pulse generating circuit P generates a clock pulse. The clock pulse is supplied to the (n)- scale counter CT on a transmission side and also sent the a receiving circuit II'. The counter CT counts the clock pulses to generate count outputs B, C and D. Then, AND gates GT1-GTn on the transmission side are opened in response to count outputs 1-(n) of the counter CT to allow (n) pieces of data to pass through them, and when those (n) data are arranged in time series at a data output terminal TT2, split (n)-multiple data E are obtained. In the receiving circuit II', on the other hand, the clock pulses sent from a transmtting circuit I' are counted by an (n)-scale counter CR to generate count outputs F, G, and H. Then, (n) gates GR1-GRn are opened in response to count outputs 1-(n) of the counter CR to obtain (n)-multiple data. |
