Busing power in the cable can alleviate the need for isolated power to be generated at each connection of a ground-isolated bus. The driver differential outputs and receiver differential inputs connect internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus whenever the driver is disabled or not powered. The drivers and receivers have active-high and active-low enables respectively, which can be externally connected together to function as a direction control.

These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage values, except differential I/O bus voltages, are with respect to network ground terminal. 6.2 ESD Ratings VALUE V(ESD) (1) (2) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS001 (1) A, B, and GND 16000 All pins 4000 Charged-device model (CDM), per JEDEC specification JESD22-C101 (2) UNIT V 1000 JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
