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).
