Single-Channel: 6N138, 6N139

Dual-Channel: HCPL2730, HCPL2731

Low Input Current High Gain Split

Darlington Optocouplers

Features

Description

■ Low current – 0.5mA

The 6N138/9 and HCPL2730/HCPL2731 optocouplers

consist of an AlGaAs LED optically coupled to a high

gain split darlington photodetector.

■ Superior CTR-2000%

■ Superior CMR-10kV/µs

■ CTR guaranteed 0–70°C

■ U.L. recognized (File # E90700)

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, HCPL2730/HCPL2731, an integrated

emitter-base resistor provides superior stability over

temperature.

■ VDE recognized (File # 120915) Ordering option V,

e.g., 6N138V

■ Dual Channel – HCPL2730, HCPL2731

Applications

■ Digital logic ground isolation

■ Telephone ring detector

■ EIA-RS-232C line receiver

■ High common mode noise line receiver

■ µP bus isolation

The combination of a very low input current of 0.5mA

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 compati-

bility is ensured to CMOS as well as high fan-out TTL

requirements. An internal noise shield provides excep-

tional common mode rejection of 10 kV/µs.

■ Current loop receiver
