Absolute Maximum Ratings
Exceeding the Absolute Maximum ratings may damage the
device.
Note:
1. Devices are inherently ESD sensitive, handling precautions are
required. Human body model rating: 1.5k
in series with 100pF.
Recommend Operating Ratings
The device is not guaranteed to operate beyond the Maximum
Operating Ratings.
Note:
2. The value of
board with 2oz. Copper, in a still air environment with T
value in any given application depends on the user’s specific board
design.
