Absolute Maximum Ratings

Note1: Stresses greater than those listed under Maximum Ratings may cause permanent damage to the

device. This is a stress rating only and functional operation of the device at these or any other conditions

above those indicated in the operation is not implied. Exposure to absolute maximum rating conditions

for extended periods may affect reliability.
