An XOR is a convenient structure to allow a control signal to invert or

Trouble is (as classically done) inverting has 3 stage delays, while
non-inverting has only 2.

Anyone know of a configuration that has symmetric delays?

Thanks!

Never rolled my own at the device level but can you drive A through a
tristate inverter and a tristate buffer and then use B to select the
output?
