Notes:
1. Exceeding the absolute maximum rating may damage the device. Stresses greater than the absolute maximum rating may cause permanent
damage to the device. Operation of the device at these or any other conditions above those specified in the operating sections of this specification is
not implied. Maximum conditions for extended periods may affect reliability.
2. The device is not guaranteed to function outside its operating rating.
3. TA = 25°C. Specification is for packaged product only.
4. Current consumption is for the single 3.3V supply KSZ8021/31RNL device only, and includes the transmit driver current and the 1.2V supply voltage
(VDD_1.2) that are supplied by the KSZ8021/31RNL.
