*Notice: Stresses above 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 those or
any other conditions above those indicated in the operational
listings of this specification is not implied. Exposure to maxi-
mum rating conditions for extended period of time may affect
device reliability.
