NOTE:
Stress greater than those listed under “Absolute Maximum Ratings” may cause permanent damage
to the device. This is a stress rating only and func tion al operation of the device at these or any other
conditions greater than those in di cat ed in the operational sections of this spec i fi ca tion is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect reliability.
