Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the

Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect

device reliability.

1. Maximum terminal current is bounded by the maximum current handling of the switches, maximum power dissipation of the package, and

maximum applied voltage across any two of the A, B, and W terminals at a given resistance.
