Ok here are some photo's of the diagrammes to make it easier for our members who can not find these TTL IC details.
This info is from my TTL Cookbook which i bought years and years ago, but occasionally these are for sale on Ebay.
Info for the 7400, 7408, 7447, 7490, 7492 and 74160 attached.
There are very good PDF files on the internet available as long the LS or SN is put in the search engine ( 74LSxx ) or ( SN 74xx )
Hope this wil help,
Regards, Raymond
