It's been years since I did any real electronics but I remember using a NAND gate as a "programmable inverter".

The signal from input A to the output is either inverted or not inverted depending on the state of input B.

No, a programmable inverter is an XOR gate or XNOR gate.

You're right, of course. I wasn't thinking about that clearly :)
