PCA9545A: Multiplexing I2C

Expert 1195 points
Part Number: PCA9545A
Other Parts Discussed in Thread: SN74LV4052A, TMUX1209

Tool/software:

I have one I²C master (uC) and 4 slave devices — all with the same default address (0x60), which can only be changed via I²C.
In small production, I used jumpers to isolate each device and change the address manually.
But this is not practical for mass production.

Would using a PCA9545A or similar I²C switch be a good solution for this?

I need to communicate with all 4 devices quickly, so fast switching is important.

Thanks!
