Description
The 6N138M/9M and HCPL2730M/31M 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, HCPL2730M/HCPL2731M, an inte-
grated 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.
– Ordering option V, e.g., 6N138VM

Absolute Maximum Ratings
(T
A
= 25°C unless otherwise specified)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

2. Current Transfer Ratio is defined as a ratio of output collector current, I
O
, to the forward LED input current,
I
F
, times 100%.
3. Pin 7 open. (6N138M and 6N139M only)
4. 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
> 2.0V). 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
< 0.8V).
5. 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.
6. 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.
7. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
