Description

The IL74/ ILD74/ ILQ74 is an optically coupled pair
with a GaAIAs infrared LED and a silicon NPN pho­totransistor. Signal information, including a DC level,

can be transmitted by the device while maintaining a
high degree of electrical isolation between input and
output.The IL74/ ILD74/ ILQ74 is especially for driving
medium-speed logic, where it may be used to elimi­nate troublesome ground loop and noise problems.
Also it can be used to replace relays and transformers
in many digital interface applications, as well as ana­log applications such as CTR modulation.

The ILD74 has two isolated channels in a single DIP
package; the ILQ74 has four isolated channels per
package.

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
operatingsystems 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.
