Note 1:

Self-protected

against transient voltages exceeding these limits for ≤ 50ns under normal operation and loads

up to the maximum rated output current.

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.
