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 and the operating ranges.

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)
