†
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.
NOTES: 1. All voltage values, except differential I/O bus voltage, are with respect to network ground terminal.
2. Tested in accordance with MIL−STD−883C, Method 3015.7
3. The maximum operating junction temperature is internally limited. Use the dissipation rating table to operate below this temperature.

The algebraic convention, in which the least positive (most negative) limit is designated as minimum, is used in this data sheet.
NOTE 4: Differential input/output bus voltage is measured at the noninverting terminal A with respect to the inverting terminal B.
