Note 1: Limits are guaranteed by 100% testing, sampling, or correlation with worst-case test conditions.

Note 2: This does not include the current from the AUI pull-down resistors, or LED status outputs.

Note 4: Does not include pre-bias current for fiber optic LED which would typically be 3mA.

Note 5: Threshold for switching from Link Fail to Link Pass (Low Light).
