Single-Channel: 6N138, 6N139

Dual-Channel: HCPL-2730, HCPL-2731

Low Input Current High Gain Split

Darlington Optocouplers

Features

Description

■ Low current - 0.5 mA

The 6N138/9 and HCPL-2730/HCPL-2731 optocouplers consist

of an AlGaAs LED optically coupled to a high gain split darling-

ton photodetector.

■ Superior CTR-2000%

■ Superior CMR-10 kV/µs

■ CTR guaranteed 0-70°C

■ U.L. recognized (File # E90700)

The split darlington conﬁguration separating the input photo-

diode and the ﬁrst stage gain from the output transistor permits

lower output saturation voltage and higher speed operation than

possible with conventional darlington phototransistor optocou-

pler. In the dual channel devices, HCPL-2730/HCPL2731, an

integrated emitter - base resistor provides superior stability over

temperature.

■ VDE recognized (File # 120915) Ordering option

V, e.g., 6N138V

■ Dual Channel - HCPL-2730

■ HCPL-2731

The combination of a very low input current of 0.5 mA and a

high current transfer ratio of 2000% makes this family particu-

larly 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 pro-

vides exceptional common mode rejection of 10 kV/µs.

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
