Filed: 1993-07-28
Abstract: PURPOSE:To simplify the circuit construction and miniaturize the circuit and reduce the power consumption by connecting terminals of a plurality of switches to each other in a prescribed order and connecting a signal line between adjacent ones of the switches. CONSTITUTION:Signals to be selected RQ1 to RQn are grouped signals to be selected which are supplied from an input/output device 10 to a signal selection circuit 12 while, on the other hand, selection signals REQ1 and REQ2 are outputted from the circuit 12 to an input/output control device 14. A signal line RQ1 and terminals 1 of switches SP1 and SP2 are connected to each other and signal lines RQ2 and terminals '' of the switch SP2 and SP 3 are connected to each other. Further, a signal line RQn is sequentially connected to a switch SPn and a switch SP (n+1). Then, in case that the signals RQ1 to RQn are inputted from the input/output device 10, the signal RQ1 passes through the switch SP1 and is transmitted as it stands to the control device 14 in the form of the signal REQ1. Subsequently, the signal RQ2 passes through the switches SP3, SP4 to be transmitted as the signal REQ2 to the control device 14. At this time, the succeeding switches are made open, to thereby provide a miniaturized circuit with a simple circuit structure.
