An integrated circuit component having an array of rows and columns of programmable coupling elements, the rows being coupled to a plurality of independent input signals and the columns being coupled to output ports through a plurality of selectors. With such circuit component the independent input signals may be selectively coupled to the output ports in accordance with the programmed state of the programmable coupling elements and in accordance with control signals fed to the selectors. Therefore, if it is desired to change the coupling of the input signals to the output ports for the given control signal a different circuit component having differently programmed coupling elements may replace the previously programmed circuit component without requiring changes to printed circuit board connectors.
