† 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 maximum rating conditions for an extended
period of time may affect device reliability.
