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.

Note 1:
LXSU has internal clamp diodes to PVSU and PGSU, LXM has internal clamp diodes to PVM and PGM, and LXSD has inter-
nal clamp diodes to PVSD and PGSD. Applications that forward bias these diodes should take care not to exceed the
devices’ power dissipation limits.
