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: LX1 has internal clamp diodes to PGND1 and OUT1. LX2 has internal clamp diodes to PGND2 and OUT2. Applications

that forward bias these diodes should take care not to exceed the IC package power dissipation limit.
