Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FAIRCHI LD’S PRODUCTS ARE NOT AUTHORIZED F OR USE AS CRITI CAL COM PONENTS IN LI FE SUPPORT DEVICES OR SY STEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAI RCHI LD SEM ICONDUCTOR CO RPORATION.
As used herein:
1. Life support devices or systems are devices or systems whic h, (a) are
intended for surgical im plant into the body or (b) support or sustain l ife,
and (c) whose failure to perform when properly used in accordance
with instructions for use provided in the labeling, can be reasonably
expected to result in a significant injury of the user.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, w ww.fairchildsemi.com,
under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are exp eriencing counterfeiting of their parts.
Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications,
and increased cost of production and manufacturing delay s. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of
counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are
listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have
full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information.
Fairchild and our Authorized Distributors will stand behind all w arranties and will appropriately address any warranty issues t hat may arise. Fairch ild will not p rovide
any w arranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buy ing direct or from authorized distributors.
