... The pass gates of the multiplexer are constructed such that the V pin can be used to limit the maximum high voltage which will be passed by the PCA9540B. This allows the use of different bus voltages on each SCx/SDx pair, so that 1.8 V, 2.5, or 3.3 V parts can communicate with 5 V parts without any additional protection. ...
