† Notice:
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those indicated
in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended
periods may affect device reliability.
