DESCRIPTION
The SFH675xT-series, is a dual channel 10 MBd optocoupler utilizing a high efficient input LED coupled with an integrated optical photodiode IC detector. The detector has an open drain NMOS-transister output, providing less leakage compared to an open collector Schottky clamped transister output. The internal shield provides a guaranteed common mode transient immunity of 5 kV/s for the SFH6756T and 15 kV/s for the SFH6757T. The use of a 0.1 F bypass capacitor connected between pin 5 and 8 is recommended.
APPLICATIONS
* Microprocessor system interface * PLC, ATE input/output isolation * Computer peripheral interface * Digital fieldbus isolation: CC-link, DeviceNet, profibus, SDS * High speed A/D and D/A conversion * AC plasma display panel level shifting * Multiplexed data transmission * Digital control power supply * Ground loop elimination
AGENCY APPROVALS
* UL1577, file no. E52744 system code Y * CUL - file no. E52744, equivalent to CSA bulletin 5A * DIN EN 60747-5-5 (VDE 0884) available with option 1

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.
