Note 2: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices

should be operated at these limits. The tables of “Electrical Characteristics” and “Recommended Operating Conditions” provide conditions for actual device operation.

Note 3: Unless otherwise specified min/max limits apply across the supply and temperature range listed in the table of “Recommended Operating Conditions”. All

Note 4: 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.
