Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent
damage to the device. These are stress ratings only, and functional operation of the
device at these or any other conditions beyond those indicated in the operational sections
of the specifi cations is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
* Mounted on FR4 board, 25mm x 25mm x 1.57mm.
