(1) Stresses beyond those listed under Absolute Maximum Rating may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under

Recommended Operating Condition. Exposure to absolute-maximum-rated conditions for extended periods may affect device

reliability.

(2) All voltage values are with respect to network ground terminal.

(3) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.

(2) Level listed above is the passing level per ANSI, ESDA, and JEDEC JS-001. JEDEC document JEP155 states that 500-V HBM allows

safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary
