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.
