Abstract

PURPOSE:To obtain a multiplexing device where the number of the intra-device wirings of a data signal and a clock signal on a transmission-side and a reception-side in the digital multiplex device is reduced. CONSTITUTION:Tristate gate circuits 50, 70 and 90 are respectively provided on intra-device signal interface parts of plural channel parts 3, a multiplexing part 10 and a separation part 20. Then, the data signal and the clock signal on the transmission-side and the reception-side are alternately communicated by transmission/reception control signals 120 and 130 from a control part 40. Since the data signal and the clock signal on the transmission-side and the reception-side are communicated by using the same intra-device wiring, the number of the intra-device wirings can be reduced compared with that of a conventional multiplexing device.
