Part Number: TCA9548A
Does TCA9548A have any issue under below operating voltage?
It is OK to operate the device in this way with VCC = 3.3 V and VDPU = 5 V on the downstream buses.
If you have any further questions please just let us know.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Max Robertson:
How about below condition?
In reply to Jason Wu4:
It would be better to operate at a lower VCC level. At VCC = 3.3 V, the "Vpass" voltage would be about 2 V (see Figure 14 in the datasheet). This means that any voltages lower than 2 V would be passed through the device. The master side's high level of 1.65 V is below this, and so the downstream channels would also have a high level of close to 1.65 V rather than the desired 5 V level.
