Note 1:
Stresses beyond those listed under Absolute Maximum Ratings receive a message on the RXP and RXN pins, plus the time the LTC4310 may cause permanent damage to the device. Exposure to any Absolute requires to process the message and pass the low to the data and clock Maximum Rating condition for extended periods may affect device buffers, plus the time required by the buffers to drive their bus pins below reliability and lifetime. 0.5 • VCC.
Note 2.
Guaranteed by design, not tested in production.
