Figure 7. Typical Star Application
Multiple PCA9517 A sides can be connected in a star configuration, allowing all nodes to communicate with each
other.
Figure 8. Typical Series Application
Multiple PCA9517s can be connected in series as long as the A side is connected to the B side. I

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 considerations on the maximum bus speed requirements.
