Request f your special attention and precautions in using the technical infmation and semiconducts described in this book () If any of the products technical infmation described in this book is to be expted provided to non-residents, the laws and regulations of the expting country, especially, those with regard to security expt control, must be observed. () The technical infmation described in this book is intended only to show the main characteristics and application circuit examples of the products, and no license is granted under any intellectual property right other right owned by our company any other company. Therefe, 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 infmation described in this book. (3) The products described in this book are intended to be used f standard applications general electronic equipment (such as office equipment, communications equipment, measuring instruments and household appliances). Consult our sales staff in advance f infmation on the following applications: Special applications (such as f airplanes, aerospace, automobiles, traffic control equipment, combustion equipment, life suppt systems and safety devices) in which exceptional quality and reliability are required, if the failure malfunction of the products may directly jeopardize life harm the human body. Any applications other than the standard applications intended. (4) The products and product specifications described in this book are subject to change without notice f modification and/ improvement. At the final stage of your design, purchasing, use of the products, therefe, ask f the most up-to-date Product Standards in advance to make sure that the latest specifications satisfy your requirements. () 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. Otherwise, we will not be liable f 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 semiconduct products. Measures on the systems such as redundant design, arresting the spread of fire preventing glitch are recommended in der to prevent physical injury, fire, social damages, f example, by using the products. (6) Comply with the instructions f use in der to prevent breakdown and characteristics change due to external facts (ESD, EOS, thermal stress and mechanical stress) at the time of handling, mounting at customer's process. When using products f which damp-proof packing is required, satisfy the conditions, such as shelf life and the elapsed time since first opening the packages.
