ABSTRACT:
A logical current switch responsive to a plurality of input logical signals having predetermined voltage swings and including in a first circuit arrangement parallel-connected bipolar transistors responsive to the logical signal levels of the input signals, and including in a second circuit arrangement a single bipolar transistor responsive to a logical function of the input signals via Schottky barrier diodes. Each of the above arrangements being connected with a further ground-biased transistor and including a Schottky barrier diode for coupling the emitter of the input signal responsive bipolar transistor to the emitter of the ground-biased bipolar transistor so as to result in circuits for producing complementary output signal level swings of a magnitude equal to the input logical signal voltage level swings.
