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.

2 Package power dissipation = (TJMAX – TA)/θJA.

Data Sheet

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.
