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).
