[stuee]

Ok found somewhere to get the bits for the ir network but there are so many types.
Could someone please look here

And tell me which one to use as on the schematic it just says 74as04.

Any help appreciated. thanks

The suffixes are package types. N is the plastic DIP type. Go to the manufacturers site for others.
