Note 1

‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed Except for ‘‘Operating Temperature Range’’

they are not meant to imply that the devices should be operated at these limits The table of ‘‘Electrical Characteristics’’ provides conditions for actual device

operation

Note 2

Note 3

All currents into device pins shown as positive out of device pins as negative all voltages referenced to ground unless otherwise noted All values shown

as max or min on absolute value basis
