VSOJ 20 pin SON22 pin VSOJ 12pin /INT Output Interrupt output (N-ch open drain ) VDD - Connected to a positive power supply. The metal case inside of the molding compound may be exposed on the top or bottom of this product. GND - Connected to a ground. This purely cosmetic and does not have any effect on quality, reliability or electrical specs. *Stop using the glue Any glue must never use it after soldering LC-package to a circuit board.This product has glass on the back side of a package.When glue invasions between circuit board side and glass side, then glass cracks by thermal expansion of glue.In this case a crystal oscillation stops.Consider glue abolition or glue do not touch to LC-package Specifications (characteristics) Refer to application manual for details.

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 the ozone layer, and global deforestation. Japan and overseas, completed the acquisition of ISO 14001 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.
