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 operations sections of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.

Characteristics

(Minimum and maximum values specified over operating case temperature range at 50% duty cycle data signal.

Typical values are measured at room temperature unless otherwise noted.)
