Request for your special attention and precautions
in using the technical information and semiconductors described in this book
(1) If any of the products or technical information described in this book is to be exported or provided to non-
residents, the laws and regulations of the exporting country, especially, those with regard to security export
control, must be observed.
(2) The technical information described in this book is intended only to show the main characteristics and
application circuit examples of the products. No license is granted in and to any intellectual property right or
other right owned by Nuvoton Technology Corporation Japan or any other company. Therefore, no
responsibility is assumed by our company as to the infringement upon any such right owned by any other
company which may arise as a result of the use of technical information de-scribed in this book.
(3) The products described in this book are intended to be used for general applications (such as office
equipment, communications equipment, measuring instruments and household appliances), or for specific
applications as expressly stated in this book.
It is to be understood that our company shall not be held responsible for any damage caused as a result of the
following special applications:
Special applications (such as for automotive, airplanes, aerospace, transport equipment, traffic signaling
equipment, combustion equipment, medical equipment and safety devices) in which exceptional quality and
reliability are required, or if the failure or malfunction of the products may directly jeopardize life or harm the
human body.
It is to be understood that our company shall not be held responsible for any damage incurred as a result of or
in connection with your using the products described in this book for any special application, unless our
company agrees to your using the products in this book for any special application.
(4) When designing your equipment, comply with the range of absolute maximum rating and the guaranteed
operating conditions (operating power supply voltage and operating environment etc.). Especially, please be
careful not to exceed the range of absolute maximum rating on the transient state, such as power-on, power-off
and mode-switching. Other-wise, we will not be liable for any defect which may arise later in your equipment.
Even when the products are used within the guaranteed values, take into the consideration of incidence of break
down and failure mode, possible to occur to semiconductor products. Measures on the systems such as
redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical
injury, fire, social damages, for example, by using the products.
(5) Comply with the instructions for use in order to prevent breakdown and characteristics change due to
external factors (ESD, EOS, thermal stress and mechanical stress) at the time of handling, mounting or at
customer's process. We do not guarantee quality for disassembled products or the product re-mounted after
removing from the mounting board. When using products for which damp-proof packing is required, satisfy the
conditions, such as shelf life and the elapsed time since first opening the packages.
(6) When reselling products described in this book to other companies without our permission and receiving
any claim of request from the resale destination, please understand that customers will bear the burden.
(7) This book may be not reprinted or reproduced whether wholly or partially, without the prior written
permission of our company.
