How it works
This design replicates the circuit inside a TI configurable logic gates 74xx1G97 (and by including an inverted output, it will work as a 74xx1G98 as well). Since there are still I/O pins left, I included two of these configurables, and also one 74xx1G79 D Flip-Flop (again, an inverted output means this will also work as a 74xx1G80).
How to test
You could refer to TI's 1G79/1G80/1G97/1G98 datasheet to test the device according to the pinout listed below.
