9.2 Typical Application
A typical application of the PCA9548A contains 1 or many separate data pull-up voltages, VCC , one for the master device and one for each of the selectable slave channels, 0 through 7. In the event where the master device and all slave devices operate at the same voltage, then the VCC pin can be connected to this supply voltage. In an application where voltage translation is necessary, additional design requirements must be considered (See the Design Requirements section).
Figure 9-1 shows an application in which the PCA9548A can be used.
Pin numbers shown are for the PW and RTW packages.
