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 to 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. A single port’s transformer consumes an additional 40mA (approximately) for 100Base-TX and 59mA for
10Base-T.
5. Measurements were taken with operating ratings.
