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. The table of “Electrical Characteristics” provide conditions for actual device operation.

Note 2: Unless otherwise specified, all voltages are referenced to ground. All currents into device pins are positive; all currents out of device pins are negative.

Note 3: Ratings apply to ambient temperature at 25˚C. Above this temperature derate N Package 13.89 mW/˚C, and M Package 9.80 mW/˚C.

Note 5: See EIA Specification RS-422 for exact test conditions.

Note 7: This is the current sourced when a high output is shorted to ground. Only one output at a time should be shorted.
