Abstract

An electro-optical coupling system comprises a light-emitting semi-conductor diode, a transistor, and means connected in parallel with the emitter-base junction of the transistor to cause the latter to conduct in response to light from the diode. Three diodes 36, 38, 40, Fig. 3, may be provided to form a logic circuit in which transistor 2 conducts when diode 34 and either of diodes 30, 32 conducts in response to a signal at the corresponding input. An AND circuit is described, Fig. 2 (not shown), as in an arrangement performing no logical function, but merely providing a coupling between electrically isolated circuits.
