Signal information, including a D 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 elimi- i7905 4 5 6 7 8 3 E 2 E 0 9 E nate troublesome ground loop and noise problems. lso it can be used to replace relays and transformers in many digital interface applications, as well as analog applications such as TR modulation. The ILD74 has two isolated channels in a single DIP package; the ILQ74 has four isolated channels per package.

VISHY IL74/ ILD74/ ILQ74 Ozone Depleting Substances Policy Statement It is the policy of Vishay Semiconductor GmbH to. 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 (987) and its London mendments (990) 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.. nnex, B and list of transitional substances of the Montreal Protocol and the London mendments respectively 2. lass I and II ozone depleting substances in the lean ir ct mendments of 990 by the Environmental Protection gency (EP) in the US 3. ouncil Decision 88/540/EE and 9/690/EE nnex, B and (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. ll operating parameters must be validated for each customer application by the customer. Should the buyer use products for any unintended or unauthorized application, the buyer shall indemnify 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.
