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
3. No heat spreader in package. The thermal junction to ambient (θ
4. Specification for packaged product only. A single port’s transformer consumes an additional about 40mA for 100Base-TX and 59mA for 10Bese-
5. Measurements were taken with operating ratings.
