DESCRIPTION
The 6N138/9 and HCPL-2730/HCPL-2731 optocouplers 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 permits lower output saturation voltage and
higher speed operation than possible with conventional darlington phototransistor
optocoupler. In the dual channel devices, HCPL-2730/HCPL2731, an integrated
emitter - base resistor provides superior stability over temperature.
The combination of a very low input current of 0.5 mA and a high current transfer
ratio of 2000% makes this family particularly useful for input interface to MOS,
CMOS, LSTTL and EIA RS232C, while output compatibility is ensured to CMOS as
well as high fan-out TTL requirements.
An internal noise shield provides exceptional common mode rejection of 10 kV/µs.
An improved package allows superior insulation permitting a 480 V working voltage
compared to industry standard 220 V.
APPLICATIONS
• Digital logic ground isolation
• Telephone ring detector
• EIA-RS-232C line receiver
• High common mode noise line receiver
• µP bus isolation
• Current loop receiver
