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

customs and tariffs, currency exchange, or strategic materials.
 AKM products are neither intended nor authorized for use as critical componentsNote1) in any safety,
life support, or other hazard related device or systemNote2), 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

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
