My suggestion for organizing your 7400 series ttl parts
Use your back button to return to the text!

This is a depiction of how I have organized my 7400 TTL Chips. The first cabinet is the parts that I have consistantly used in my designs. The second cabinet is my "overflow". It is parts I have occasionally needed over the years. That cabinet is combined with "overflow" analog ICs and semiconductors also. This is strictly a suggestion to help you get started organizing them.
