Where to buy chips?

I tried mouser and digi key. I type in 7490n and it come back with no results. Is there another name for it?

I need to order 7490n, 4511, 330o resistors, and a crystal. Is there anyplace i can get this stuff from?

Using DigiKey's part search. I would probably use the 74LS90 or the CMOS versions

Also works with SN7490 you need a full part number. I used Mouser as an example.
