Absolute Maximum Ratings

(T

= 25ºC unless otherwise speciﬁed)

A

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.

2. Derate linearly above 87°C, free air temperature at a rate of 0.77mW/°C

3. No derating required across temperature range.

4. Functional operation under these conditions is not implied. Permanent damage may occur if the device is subjected to conditions outside these ratings.
