isolation are achieved by coupling an LED with an
integrated high gain photo detector in a SOIC-8
package. Separate pins for the photo diode and output
stage enable TTL compatible saturation voltages with
high speed operation. Photodarlington operation is
• DIN EN 60747-5-2 (VDE0884)
Available with Option 1
• CSA 93751
achieved by tying the V and V terminals together.
Access to the base terminal allows adjustment to the
gain bandwidth.

APPLICATIONS
• Logic Ground Isolation -TTL/TTL, TTL/CMOS,
CMOS/CMOS, CMOS/TTL
The SFH6318T 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 SFH6319T 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.
• EIA RS 232C Line Receiver
• Low Input Current Line Receiver Long Lines, Party
Lines
• Telephone Ring Detector
• 117 VAC Line Voltage Status Indication - Low Input
Power Dissipation
• Low Power Systems - Ground Isolation
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.

Note:
1) Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm/dt on the leading edge of the common mode
pulse, 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).
2)
In applications where dv/dt may exceed 50,000 V/μs (such as state discharge) a series resistor, RCC should be included to protect IC from
destructively high surge currents. The recommended value is Refer to Figure 2.
RCC ≅ [(IV)/0.15 IF (mA)] kΩ.

Vishay Semiconductors
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.
