I'm looking for a diff-pair mux / analog switch (can be 1:2 or 1:3), which by design routes the common port to one of the opposite ports even when the IC is not powered.
Sort of a "normally-closed" state in unpowered mode.
Should be suitable for USB3 signals. (Up to 5Ghz)
Is there any single IC meeting these requirements?
Unfortunately we don't have !
