Hi team

Can TCA9617B connect to multiple Slaves? And how many Salves can TCA9617B connect to?

Customer wants to use one TCA9617B with 6 Slaves.

If TCA9617B can't support multiple Slaves, could you tell other devices that can support multiple slaves?

There is no limit on the number of slaves. The size of a bus is limited by its capacitance (the test conditions are 200 pF on the A side and 400 pF on the B side).

Takahashi-san,

As Clemens said, the limitation for nodes on the bus is the overall capacitance. Please let us know if you have any other questions.
