ABSTRACT:
A digital signal exchange equipment is disclosed which is constructed of a combination of selector modules each constituted by a plurality of gate arrays as a parallel unit in a column direction. The respective gate array comprises a first gate for selecting one line from an n number of first input lines and connecting it to an output line, a second gate for selecting one line from an output line of the first gate and one second input line and connecting it to the second gate and a flip-flop for wave-shaping an output of the second gate and, at the same time, taking synchronization among the respective gate array. The selector module as set forth above is constructed of a semiconductor circuit device. When, in particular, a plurality of selector modules are combined together, they are arranged as a k-column/l-row array in which input bus lines are each connected to each common row and an n number of output lines are connected for each row to an n number of second input lines of the next-row selector module.
