* PFI input voltage must not exceed 4.5V.

** The “VIN < VDD+1.0V” restriction does not apply to the SCL and SDA inputs which do not employ a diode to VDD.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only,

and the functional operation of the device at these or any other conditions above those listed in the operational section of this

specification is not implied. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability.
