*Note:
Stresses above those listed under "2.1 Absolute Maximum Ratings" may cause permanent damage to the device. This
is a stress rating only, and functional operation of the devices at those or any other conditions above those indicated in
the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods
may affect device reliability.
