DESCRIPTION
High common mode transient immunity and very high current
ratio together with 5300 V
RMS
insulation are achieved by
coupling and LED with an integrated high gain photo detector
in an eight pin dual-in-line package. Separate pins for the
photo diode and output stage enable TTL compatible
saturation voltages with high speed operation.
Photo darlington operation is achieved by tying the V
CC
and
V
O
terminals together. Access to the base terminal allows
adjustment to the gain bandwidth.
The 6N138 is ideal for TTL applications since the 300 %
minimum current transfer ratio with an LED current of 1.6 mA
enables operation with one unit load-in and one unit load-out
with a 2.2 kΩ pull-up resistor.
The 6N139 is best suited for low power logic applications
involving CMOS and low power TTL. A 400 % current
transfer ratio with only 0.5 mA of LED current is guaranteed
from 0 °C to 70 °C.
Caution: Due to the small geometries of this device, it should be
handled with Electrostatic Discharge (ESD) precautions. Proper
grounding would prevent damage further and/or degradation which
may be induced by ESD.

Notes
(1)
Common mode transient immunity in logic high level is the maxium tolerable (positive) dVcm/dt on the leading edge of the common mode
pulse, V
CM
, to assure that the output will remain in a logic high state (i.e. V
O
> 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, V
CM
to assure that the output will remain
in a logic low state (i.e. V
O
< 0.8 V).
(2)
In applications where dV/dt may exceed 50 000 V/µs (such as state discharge) a series resistor, R
CC
should be included to protect I

from
destructively high surge currents. The recommend value is R

OZONE DEPLETING SUBSTANCES POLICY STATEMENT
It is the policy of Vishay Semiconductor GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with
respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone
depleting substances (ODSs).
The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid their use
within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances.
Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in
the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively.
2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency
(EPA) in the USA.
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively.
Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do
not contain such substances.
We reserve the right to make changes to improve technical design
and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each customer application by the
customer. Should the buyer use Vishay Semiconductors products for any unintended or unauthorized application, the buyer shall
indemnify Vishay Semiconductors against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any
claim of personal damage, injury or death associated with such unintended or unauthorized use.
