(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 used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully

functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

(2)

All voltage values except differential I/O bus voltages are with respect to the local ground terminal (GND1 or GND2) and are peak

voltage values.

(3)

Maximum voltage must not exceed 6V

(1)

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

(2)

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