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.

ELECTRICAL CHARACTERISTICS
Unless otherwise specified T
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 T
Note 3: This does not include the current from the AUI pull down resistors or the LED output pins.
