Figure 5. Typical series application
Multiple PCA9517s can be connected in series as long as the A side is connected to the B side. I

C-bus slave devices can be connected to any
of the bus segments. The number of devices that can be connected in series is limited by repeater delay/time of flight considereations on the
maximum bus speed requirements.
