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).
