Stresses above those listed under Absolute Maximum Ratings

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

rating only and 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.

THERMAL RESISTANCE

θJA is defined by JEDEC specification JESD-51 and the value is

dependent on the test board and test environment.

1 JEDEC 2S2P test board, still air (0 m/sec airflow).

ESD CAUTION

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 and W terminals at a given

resistance.

2 Pulse duty factor.
