TS5A23159: Can the TS5A23159DGSR be used as an IIC switch?

Hi,

Can the TS5A23159DGSR be used as an IIC switch?
It is assumed that two master devices are used by switching for a Slave Device.

In that case, the power supply of TS5A23159DGSR is 3.3V.
IIC communication assumes 1.8V 400kHz.

I think that it can be realized with the circuit diagram below,
is there any problem in using the TS5A23159DGSR?

Thans,

You can use any mux that supports the required voltages and frequencies. The TS5A23159 certainly does. The TS5A23157 or TS5A623157 would be a little bit cheaper.

(In theory, I²C supports multiple masters. In practice, your masters' software might not.)

Hi,

Thank you for your answer and introducing better parts.

(I asked for a multi-master, but our software engineer wanted a separate master.)

Thanks,
