Description
The IL256A is an AC input phototransistor optocou- pler. The device consists of two infrared emitters con- nected in reverse parallel and coupled to a silicon NPN phototransistor detector. These circuit elements are constructed with a stan- dard SOIC-8 foot print. The product is well suited for telecom applications such as ring detection or off/on hook status, given its bidirectional LED input and guaranteed current trans- fer ratio (CTR) minimum of 20 % at I F = 10 mA. Order Information For additional information on the available options refer to Option Information. Absolute Maximum Ratings Tamb = 25 °C, unless otherwise specified Stresses in excess of the absolute Maximum Ratings can cause per manent damage to the device. F unctional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute Maximum Rating for extended periods of the time can adversely affect reliability.

www.vishay.com Document Number 83620 Rev. 1.4, 22-Apr-04 VISHA YIL256AT 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 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.
