(1)
Stresses beyond those listed under Absolute Maximum Ratings 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 Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
(2)
All voltage values here within are with respect to the local ground pin (GND1 or GND2) and are peak voltage values.
(3)
Maximum voltage must not exceed 6 V.

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.

This represents the maximum frequency with the maximum bus load (C) and the maximum current sink (IO). If the system has less bus
capacitance, then higher frequencies can be achieved.
