I'm trying to build the 7447 BCD from its
schematic, but I don't understand what to do with the BI/RBO, RBI, LT
inputs. I tried grounding them to no success. HELP!
When I plug a ground into those inputs the light blinks. I'm just starting to learn about datasheets so I haven't a clue on how to read the one from ti.

Thanks alot, It really helps. My number shows on the LED but it flickers to 8, says If I have a 2, f and c will flicker on and off, if I have 0, g will flicker. Its driving me mad, I checked my and triple checked my connections they're all fine.
ive been playing with them in a simulator it ran OK with 12v but i guess i'll have to take your word for it, you\re the expert here. i was scared to try it in-circuit before this lol.
