ABSOLUTE MAXIMUM RATINGS
OPERATING CONDITIONS
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 1: Limits are guaranteed by 100% testing, sampling or correlation with worst case test conditions.
Note 2: Low Duty cycle pulse testing is performed at TA.
Note 3: This does not include the current from the AUI pull down resistors or the LED output pins.
