Note 1
Absolute maximum ratings are those values 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
Note 2
All currents into device pins are positive all currents out of device pins are negative All voltages referenced to ground unless otherwise specified
Note 3
All typicals are given for V
