ABSOLUTE MAXIMUM RATINGS

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.
