*Notice: Stresses above those listed under ‘Maximum ratings’
may cause permanent damage to the device. This is a stress rat-
ing only and functional operation of the device at those or any
other conditions above those indicated in the operational listings
of this specification is not implied. Exposure to maximum rating
conditions for extended period of time may affect device reliability
