may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating
temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon
reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/Derating Concept and Methods) and
individual reliability data (i.e. reliability test report and estimated failure rate, etc).
