There are just so many voltages to move from 3.3 to 5! The key index word is not level shifter (that's too analog apparently), but "logic translator". I have some other candidate parts for the signals: SN74LVC8T245 and 74LVXC3245. You can pretty much take a "3" in any other suppliers parts and put a "T" in there for TIs.
The bidirectional signals are BB, TT0, TT1, TS. I'm rather confident that TS will never be an input because there's not cache snooping.
