Over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: All voltage values, except differential I/O bus voltage, are with respect to the network ground terminal.
Note 3: The maximum power dissipation is a function of T
P
Note 4: ESD rating based upon human body model, 100 pF discharged through 1.5 kΩ.
Note 5: Voltage limits apply to DI, DE, RE pins.
Note 6: Differential input/output bus voltage is measured at the non-inverting terminal A with respect to the inverting terminal B.
Note 7: |∆V
