ABSTRACT:
A multistage switch control circuit allows unit switches to be set at a higher speed than conventional multistage switch control circuits. Higher-order half first and second control elements are connected to a first section of a bus to form a first cluster, while lower-order half third and fourth control elements are connected to a second section of the bus to form a second cluster. A bus switch which functions as a cluster formation means is arranged between the first section and the second section of the bus to perform the connection/separation of the first section and the second section. The first to fourth control elements transmit switch control signals to corresponding unit switches, respectively, in each stage.
