ST pin = HIGH or “Open” : Specified frequency output.
ST pin = LOW : Output is high impedance, oscillation stop.
SG-711series
OE pin = HIGH or “Open” : Specified frequency output.
OE pin = LOW : Output is high impedance
To maintain stable operation, provide a 0.01uF to
0.1uF by-pass capacitor at a location as near as
possible to the power source terminal of the crystal
product (between Vcc - GND).

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
improvements. The environmental management system (EMS)
operates under the ISO 14001 environmental management standard.
All of our major manufacturing and non-manufacturing sites, in
Japan and overseas, completed the acquisition of ISO 14001
certification.
ISO 14000 is an international standard for environmental
management that was established by the International
Standards Organization in 1996 against the background of
growing concern regarding global warming, destruction of
the ozone layer, and global deforestation.
WORKING FOR HIGH QUALITY
In order provide high quality and reliable products and services
than meet customer needs,
Seiko Epson made early efforts towards obtaining ISO9000 series
certification and has acquired ISO9001 for all business
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.
Contains Pb in products exempted by EU RoHS directive.
(Contains Pb in sealing glass, high melting temperature type solder or other.)
►Designed
for automotive applications such as Car Multimedia, Body Electronics, Remote Keyless Entry etc.
►Designed
for automotive applications related to driving safety (Engine Control Unit, Air Bag, ESC etc ).
ISO/TS16949 is the international standard that added the
sector-specific supplemental requirements for automotive
industry based on ISO9001.
