Note: Using continuously under heavy loads (e.g. the application of high
temperature/current/voltage and the significant change in temperature,
etc.) 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).
