*Stress greater than 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
these or any other conditions greater than those indicated in operational sections of this
specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
