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.

Notes

1. Current Transfer Ratio is defined as a ratio of output collector current, IO, to the forward LED input current, IF, 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
mon mode pulse signal VCM, to assure that the output will remain in a logic high state (i.e., VO>2.0 V). Common mode transient
immunity in logic low level is the maximum tolerable (negative) dVcm/dt on the trailing edge of the common mode pulse signal,
VCM, to assure that the output will remain in a logic low state (i.e., VO<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
together.

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

I

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