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 devices

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

Note 2: Unless otherwise specified Min/Max limits apply across the −55˚C to +125˚C temperature range.

Note 3: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to ground unless otherwise specified.

Note 4: Only one output at a time should be shorted.

Note 5: Rating applies to ambient temperatures up to +125˚C. Above 125˚C ambient, derate linearity at 120˚C/W.
