Abstract
Selectable signal connection provisions are made for passing signals relative to logic circuitry of digital bipolar semiconductor integrated circuits. Each such provision has formed on the chip for each selectable signal connection, an active circuit element whose conduction state relative to signals concerned is controlled by applied circuit conditions. The conditions are selected by operative control circuitry responsive to a configuring or selection signal applied temporarily thereto for switching between stable states and thus determining the conduction state of the active circuit element.
