I have a project in my course.. Its all about the 74LS47 and 74LS90 ICs..
I need their Pin configuration the truth table and the operation to be used.. I know its very easy, but I didnt have any background on this.. Im only 16 YRS OLD.. taking up Computer engineering.. I need this, because its our project for Final.. Please help me..

 

you know there is a think called "google" on the net that if you ask it a question it will return the answer.

just search for those components and view the (pdf) datasheets!!

I know we all see this post and shout GOOGLE! at the screen,
however querying a search engine is an art all by itself, besides
he's new and deserves a least one break :lol:

Same problem from last year?

i have allways found that if you tack on the letters pdf to the end your google querry , you get just the PDF's..

 

well if you want google to just return a certain filetype you should try
