Incorrect. The simple FET switch is just a logical equivalent circuit is non inverting but is not the actual design, as a switch does no level shifting at all.
It is correct to say it is two (2) back to back tri-state buffers to make it bidirectional to shift between 3.3V and 5.0V for ports A & B, each being exclusively enabled or neither using tri-state.
Ah, thanks for the clarification, Tony. In that case, you're saying that the diagram that comes with the datasheet is merely a logically equivalent circuit and not the actual implementation?
In reality, the implementation is most-likely two back-to-back tristate buffers that do the level shifting and bidirectional communication?

That is very interesting Tony, but if we look in the various TI Application Notes associated with the SN74CBTD3384, we come across this document: https://www.ti.com/lit/an/scda003b/scda003b.pdf
At the top of page 6, it clearly states:
The CBT bus switches consist of an N-channel MOSFET with its drain and source connected from input to output.
I think that the quick answers are:
Yes.
Read the application notes.
I would also add the caveat that it would be a good idea to test that the device does what you really want before using it in a final design, especially if the application is not as a bus switch.
