Hi all,

For my current electronic project I need some 74LS173N. I read the datasheet and wired everything up on my breadboard but I didn't get it to work like it's supposed to be.

I found this http://forum.allaboutcircuits.com/threads/ic-74ls173n.97895/ website with this ciricut :

I wired it up like this but it still doesn't work.

Does anybody have an idea why or how to get fix the problem ?

Thanks for reading and your help!
