Note:

Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even

destruction.

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).

Note 1: 180 mW in the range of Ta = -40 to 85 . From Ta = 85 to 125  a derating factor of -3.25 mW/ shall be

applied until 50 mW.
