This purely cosmetic and does not have any effect on quality, reliability or electrical specs. Note. OE pin (PTF,PCE,PDE) To maintain stable operation, provide a 0.01uF to OE pin = "H" or "open" : Specified frequency output. 0.1uF by-pass capacitor at a location as near as OE pin = "L" : Output is high impedance. possible to the power source terminal of the crystal ST pin (SCE) product (between Vcc - GND). ST pin = "H" or "open" : Specified frequency output. ST pin = "L" : Output is low level ,oscillation stops.

PROMOTION OF ENVIRONMENTAL MANAGEMENT SYSTEM CONFORMING TO INTERNATIONAL STANDARDS At Seiko Epson, all environmental initiatives operate under the Plan-Do-Check-Action (PDCA) cycle designed to achieve continuous ISO 14000 is an international standard for environmental improvements. The environmental management system (EMS) management that was established by the International operates under the ISO 14001 environmental management standard. Standards Organization in 1996 against the background of All of our major manufacturing and non-manufacturing sites, in growing concern regarding global warming, destruction of Japan and overseas, completed the acquisition of ISO 14001 the ozone layer, and global deforestation. certification. WORKING FOR HIGH QUALITY In order provide high quality and reliable products and services than meet customer needs, ISO/TS16949 is the international standard that added the Seiko Epson made early efforts towards obtaining ISO9000 series sector-specific supplemental requirements for automotive certification and has acquired ISO9001 for all business industry based on ISO9001. establishments in Japan and abroad. We have also acquired ISO/TS 16949 certification that is requested strongly by major automotive manufacturers as standard. ►Explanation of the mark that are using it for the catalog ►Pb free. ►Complies with EU RoHS directive. *About the products without the Pb-free mark.
