Note 6:
Absolute maximum ratings are limits beyond which the life of the integrated circuit may be impaired. All voltages unless otherwise specified are measured with
respect to ground.
Limits are guaranteed by 100% testing, sampling, or correlation with worst-case test conditions.
Low Duty cycle pulse testing is performed at TA.
This does not include the current from the AUI pull down resistors, the transmit pins TxTP+ and TxTP– or the LED output pins.
LED drivers can sink up to 20mA, but VOL will be higher.
This current will result in a 2.5V peak output voltage on unshielded twisted pair cable when connected through an external filter and transformer as shown in Figure 12.
