1 Maximum terminal current is bound by the maximum applied voltage across

any two of the A, B, and W terminals at a given resistance, the maximum

current handling of the switches, and the maximum power dissipation of the

package. VDD = 5 V.

2 Package power dissipation = (T

JMAX − TA)/θJA.

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.
