Notes:
1. Exceeding the absolute maximum rating may damage the device. Operating at maximum conditions for extended periods may affect device reliability.
2. The device is not guaranteed to function outside its operating rating. Unused inputs must always be tied to an appropriate logic voltage level
(Ground to VDD)
3. No (HS) heat spreader in this package.
4. Specification for packaged product only.
5. There is 100% data transmission in full-duplex mode and a minimum IPG with a 130-meter cable.
