*Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress
rating on
ly and functional operation of the device or any other conditions above those indicated in the operational sections of this
specification is not implied. Exposure to the absolute maximum rating conditions for extended period may affect device reliability.
