Hello,

 

I have some questions about PCA9547D.

1,Does the slave side of this IC support many power supplies?

(by way of example ch0->3.3V Bus and ch1->5.0V using?)

2,What should the power supply of this IC select as the material?

3,When I set the power supply of the IC low, is there any limit for connection of the master side and the slave side?

 

Thank you,

Ehira
