... The buffer extends the bus load limit by buffering both the SCL and SDA lines, allowing the maximum permissible bus capacitance on both sides of the buffer. The PCA9605 includes a unidirectional buffer for the clock signal, and a bidirectional buffer for the data signal. Slave devices which employ clock stretching are therefore not supported ...

... The power supply voltage for the PCA9605 may be any voltage in the range 2 5.5 V. The IC supply must be common with the supply for the bus. Hysteresis on the ports is a percentage of the IC’s power supply, hence noise margin considerations should be taken into account when selecting an operating voltage. ...

... Sxx_IN side of the IC. However, to locate a master on the Sxx_OUT side and have that master be able to communicate with devices on the Sxx_IN side, it must either have direct control over the direction pin (DIR) of the PCA9605 must request another controlling master to change the direction. In IRQ to signal to U2 that requests a direction change. Once in control, it could alternatively use the bus to signal ‘ ...
