Description
The 6N138/9 and HCPL2730/HCPL2731 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, HCPL2730/HCPL2731, an integrated
emitter-base resistor provides superior stability over
temperature.
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.

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 > 2.0V). 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 < 0.8V).
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 shor ted
together.
6. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
