... Using multiple PCA9518A parts, any width hub (in multiples of five) using the expansion pins. The PCA9518A is a wider voltage range (2 3.6 V) version of the PCA9518 and also improves partial power-down performance, keeping I state when V A PCA9518 cluster cannot be put in series with a PCA9515/16 or with another PCA9518 cluster ...

... SDA0 SDA1 SDA2 EN1 EN2 Fig 1. Block diagram of PCA9518A A more detailed view of Fig 2. Buffer detail The output pull-down voltage of each internal buffer is set for approximately 0.5 V, while the input threshold of each internal buffer is set about 0.07 V lower, when the output is internally driven LOW. This prevents a lock-up condition from occurring. ...

... The PCA9518A CMOS integrated circuit contains five multi-directional, open-drain buffers specifically designed to support the standard low-level contention arbitration of the 2 I C-bus. Except during arbitration or clock stretching, the PCA9518A acts like a pair of non-inverting, open-drain buffers, one for SDA and one for SCL. Refer to 6.1 Enable The enable pins EN1 through EN4 are active HIGH and have internal pull-up resistors ...
