Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

ABSOLUTE MAXIMUM RATINGS
Note 1: Signals on COM_, NO_, NC_, SEL1, and SEL2 exceeding V
DD
or GND are clamped by internal diodes. Limit forward-
diode current to the maximum current rating.
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a
4-layer board. For detailed information on package thermal considerations, refer to
