This product is weak for static electricity by designed with high-speed integrated circuit so protect against static electricity when handling. 2. By-pass capacitor of 0.1 µF is used between VCC and GND near device. Also, ensure that the distance between the leads of the photocoupler and capacitor is no more than 10 mm. 3. Avoid storage at a high temperature and high humidity. 5 4590 Patrick Henry Drive Santa Clara, CA 95054-1817 Telephone: (408) 919-2500 Facsimile: (408) 988-0279 Subject: Compliance with EU Directives CEL certifies, to its knowledge, that semiconductor and laser products detailed below are compliant with the requirements of European Union (EU) Directive 2002/95/EC Restriction on Use of Hazardous Substances in electrical and electronic equipment (RoHS) and the requirements of EU Directive 2003/11/EC Restriction on Penta and Octa BDE.
