Dual 1 Form A

Stresses in excess of the Absolute Maximum Ratings

can cause permanent damage to the device. These are

absolute 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 this

document. Exposure to Absolute Maximum Ratings for

extended periods of time can adversely affect reliability.

* Refer to Current-Limit Performance Application Note for a discussion on relay operation during transient currents.
