Notes:
1. Exceeding the absolute maximum rating may damage the device.
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 or V
DD).
3. No heat spreader in package. The thermal junction to ambient (θ
JA
) and the thermal junction to case (θ
JC
) are under air velocity 0m/s.
4. Specification for packaged product only. There is no an additional transformer consumption due to use on chip termination technology with
internal biasing for 10Bese-T and 100Base-TX.
5. Measurements were taken with operating ratings.
