This interface constitutes a matching of the output signals of a first circuit, made of GaAs for example, with the limit values of the input signals of a second digital circuit, made of silicon for example. It has a current amplifier which receives the output signal of the GaAs circuit. The voltages at the high level are controlled by a diode in series with a transistor which is then on. At the low level, the transistor is off, and it is two diodes, in parallel with the transistor, that control the output voltage. This interface is integrated into the chip of the digital circuit, made of GaAs. Single figure.
