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.
