*Note: 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 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.
