■ Dual Channel - HCPL-2730
■ HCPL-2731
The 6N138/9 and HCPL-2730/HCPL-2731 optocouplers consist
of an AlGaAs LED optically coupled to a high gain split darlington photodetector.
Applications
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.
■
■
■
■
■
■
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.

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) dVcm/dt on the leading edge of the common 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, CI-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.
