HIGH GAIN SPLIT 

DARLINGTON OPTOCOUPLERS

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

1. Current Transfer Ratio is defined as a ratio of output collector current, I

O, 

to the forward LED input current, I

F

, times 100%.

2.  Pin 7 open. (6N138 and 6N139 only)

3. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV

cm

/dt on the leading edge of the 

common mode pulse signal, V

CM

, to assure that the output will remain in a logic high state (i.e., V

O

&

2.0 V). Common mode

transient immunity in logic low level is the maximum tolerable (negative) dV

cm

/dt on the trailing edge of the common mode pulse 

signal, V

CM

, to assure that the output will remain in a logic low state (i.e., V

O

'

0.8 V).

4. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are shorted together.

5. For dual channel devices, C

I-O

is measured by shorting pins 1 and 2 or pins 3 and 4 together and pins 5 through 8 shorted together.

6. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
