Operating conditions
All specifications are at an ambient temperature of 25
°
C. Extreme operating temperatures can
significantly impact specification values. Applications operating near the temperature limits should be
tested to ensure the specification.
Table2.4 operating temperature range
Operating beyond the specified operating conditions can affect device reliability.
