Total power dissipation See Dissipation Rating Table
(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values, except differential I/O bus voltages, are with respect to GND.
(3) Tested in accordance with MIL-STD-883C, Method 3015.7
(4) The maximum operating junction temperature is internally limited. Uses the dissipation rating table to operate below this temperature.

(1) Differential input/output bus voltage is measured at the noninverting terminal with respect to the inverting terminal.
(2) The algebraic convention, in which the least positive (most negative) limit is designated as minimum, is used in this data sheet.
