PURPOSE:To obtain a small-sized, economical and high-speed control circuit which employs an integrated circuit by setting control information in parallel in a unit of a switch train sharing an output circuit. CONSTITUTION:In a switch matrix, one switch factor is constituted of a serial shift register SR and a switch element (s) and said switch factor, in this case, is arranged to a 2X2 matrix. I1 and I2 show input circuits and 01 and 02 show output circuits. They are connected so that data can be independently transferred in the columnar direction along the serial shift register output circuit, namely, so that SR11 and SR21, SR12 and SR22 can constitute serial shift registers respectively. the input circuit Ii (i=1, 2) and the output circuit Oj (j=1, 2) are connected to an input of the switch element sij (j=1, 2) and an output of the switch element sij (1, 2), respectively and commonly. By this system, a certain output circuit can be opened and other input circuit can be connected in parallel. |
