Hi, Roger
Supposing your leds are 5v powered ...
inserting 3x "1N4148" in series in EACH "base" connexion, AND two resistors ( equal high value ) to set "third state" output to V+/2 ...
that should work !!!

PS: dis, tes montages tordus ..., tu vas les pècher où ??? ... LOL !!!

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
