6N138

Fabricant : Vishay

Description :
The 6N138 consist of an AlGaAs LED optically coupled to a high gain split darlington photodetector. The split darlington configuration separating the input photodiode and the first stage gain from the output transistor pe rmits lower output saturation voltage and higher speed operation than possible with conventional darlington phototransistor optocoupler. Applications Digital logic ground isolation Telephone ring detector High common mode noise line receiver µP bus isolation Current loop receiver
