R485-Type Lightwave Receiver with Clock Recovery

for 2.488 Gb/s Applications

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess

of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.
