ABSTRACT:
A driving logic circuit having input and output terminals and first and second power terminals is described in combination with an interfacing means for making the driving logic circuit compatible with a driven logic circuit. This is accomplished by providing a first D.C. power source means which is connected across the first and second power terminals, and a second D.C. power source means which is connected in opposition to the first D.C. power means. With this arrangement the D.C. power to the power terminals is shifted to the extent of the voltage of the second D.C. power source means so as to be made compatible with the driving voltages required to drive the driven logic circuit.
