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 network ground terminal.
Note 3:
The maximum power dissipation is a function of T

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
