TTL Cookbook by Don Lancaster

thank you

Yes, Don Lancaster's TTL Cookbook is pretty much considered the "Bible" for hobbyists working with TTL. But don't discount TTL databooks from manufacturers such as Motorola, National Semiconductor, Fairchild, Signetics, Philips, NEC, Texas Instruments and others, especially older ones that you may find on ebay and other sources. I'd have to say that I learned about 90% of my digital and TTL knowledge from databooks and not textbooks.

I second that from blueroomelectronics.

TTL Cookbook by Don Lancaster has a wealth of information.

Also have a look at some TTL clock threads on this board in which datasheets are given for 7400, 7490, 7447 IC's .

Important with TTL is decoupling of each IC with a 100nF ceramic or tantalum capacitor.

I strongly recommend moving on to CMOS as soon as possible as TTL are power hungry and obsolete.

Aslo try to get LS versions where possible, they use less power and are compatible with the old TTL.
