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).
