Note 1: 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.
Note 2: Limits are guaranteed by 100% testing, sampling, or correlation with worst-case test conditions.
Note 3: Low Duty cycle pulse testing is performed at TA.
Note 4: This does not include the current from the AUI pull down resistors, the transmit pins TxTP+ and TxTP– or the LED output pins.
Note 5: LED drivers can sink up to 20mA, but VOL will be higher.
Note 6: 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.
