Note 1
‘‘Absolute Maximum Ratings’’ are those beyond which the safety of the device cannot be guaranteed They are not meant to imply that the device should
be operated at these limits The tables of ‘‘Electrical Characteristics’’ provide conditions for actual device operation
Note 2
All currents into device pins are positive all currents out of device pins are negative All voltages are referenced to device ground unless otherwise
specified
