IMPORTANT NOTICE
These products and their specifications are subject to change without notice.
When you consider any use or application of these products, please make
inquiries the sales office of Asahi Kasei Microdevices Corporation (AKM) or
authorized distributors as to current status of the products.
Descriptions of external circuits, application circuits, software and other related
information contained in this document are provided only to illustrate the
operation and application examples of the semiconductor products. You are
fully responsible for the incorporation of these external circuits, application
circuits, software and other related information in the design of your
equipments. AKM assumes no responsibility for any losses incurred by you or
third parties arising from the use of these information herein. AKM assumes no
liability for infringement of any patent, intellectual property, or other rights in

Any export of these products, or devices or systems containing them, may
require an export license or other official approval under the law and
regulations of the country of export pertaining to customs and tariffs, currency
exchange, or strategic materials.
AKM products are neither intended nor authorized for use as critical
components
Note1)
in any safety, life support, or other hazard related device or
system
Note2)
, and AKM assumes no responsibility for such use, except for the
use approved with the express written consent by Representative Director of
AKM. As used here:
Note1) A critical component is one whose failure to function or perform
may reasonably be expected to result, whether directly or indirectly, in the
loss of the safety or effectiveness of the device or system containing it,
and which must therefore meet very high standards of performance and
reliability.
Note2) A hazard related device or system is one designed or intended for
life support or maintenance of safety or for applications in medicine,
aerospace, nuclear energy, or other fields, in which its failure to function
or perform may reasonably be expected to result in loss of life or in
significant injury or damage to person or property.
It is the responsibility of the buyer or distributor of AKM products, who
distributes, disposes of, or otherwise places the product with a third party, to
notify such third party in advance of the above content and conditions, and
the buyer or distributor agrees to assume any and all responsibility and
liability for and hold AKM harmless from any and all claims arising from the
