Electrical Characteristics — Serial Management Bus Interface
Over recommended operating supply and temperature ranges unless other specified.
Note 9: Recommended value. Parameter not tested in production.
Note 10: Recommended maximum capacitance load per bus segment is 400pF.
Note 11: Maximum termination voltage should be identical to the device supply voltage.
Note 12: Compliant to SMBus 2.0 physical layer specification. See System Management Bus (SMBus) Specification Version 2.0, section 3.1.1 SMBus common
AC specifications for details.
