(1)

Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute maximum ratings do not imply

functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions.

If briefly operating outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not

sustain damage, but it may not be fully functional. Operating the device in this manner may affect device reliability, functionality,

performance, and shorten the device lifetime.

(2)

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

(3)

Assured by design.

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
