Electrical Characteristics (KS8999)
100BaseTX Transmit (measured differentially after 1:1 transformer)
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 HS (heat spreader) in package.
4. Specification for packaged product only.
