Drawn as logic instead of transistors, it looks like this:


simulate this circuit – Schematic created using CircuitLab

The bottom branch is A & !B & C, the top branch is !A & B & !C, so the final expression is

$$OUT = A \overline{B} C + \overline{A} B \overline{C}$$

It isn't clear why this was implemented as multiplexers rather than a more conventional SOP circuit.
