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.

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.

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

LIFE SUPPORT POLICY
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used herein:
1. Life support devices or systems are devices or systems which, (a) are
intended for surgical implant into the body or (b) support or sustain life,
and (c) whose failure to perform when properly used in accordance
with instructions for use provided in the labeling, can be reasonably
expected to result in a significant injury of the user.
2. A critical component in any component of a life support, device, or
system whose failure to perform can be reasonably expected to
cause the failure of the life support device or system, or to affect its
safety or effectiveness.
ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,
under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts.
Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failedapplications,
and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of
counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are
listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have
full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technicaland product information.
Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide
any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buying direct or from authorized distributors.
