A switching array as described for connecting ones of a plurality of data sources to ones of a plurality of data sinks. The array includes source data busses which transmit from a connected source, data words, a connection mask and a connection designator. The connection mask has bit positions that map to individual data sinks. A multiplexer/control circuit module is associated with each individual data sink for controlling the interconnection of the data sink to a source data bus. Each multiplexer/control circuit module is connected to each source data bus and is responsive to an active state connection mask bit and a connection designator on a first source data bus, to establish a connection between an associated sink and the first source data bus. This configuration enables the multiplexer/control circuit module to establish a connection without reference to any other multiplexer/control circuit.
