O TOSHIBA is continually working to improve the quality and the reliability of its products. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent eledrical sensitivity and vulnerability to physica!.stress. It is the responsibility of the buyer, when utilizing TOSHIBAproduas, to observe standards of safety, and to avoid situations in which a malfunaion or failure of a TOSHIBA produa could cause loss of human life, bodily injury or damage to property. In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as set forth in the most recent products specifications. Also, please keep in mind the precautions and conditions set fortH in the TOSHIBA Semiconductor Reliability Handbook.
