Maybe I should specify my question ... I need to know
at what date these chips where at first available -
not just the era. A good single IC to use could be the
74181 ALU.
Around 71. Then the H, S, LS, ALS and F parts.
I have a 74
TTL design guide at home, so I'll check it too.
The oldest datasheet I could find says Dec 1972 for the 74S181
Sounds close to right. The S however was later the basic 74181
was first. Infact the July 1972 issue of Ham Radio Has a supplier
selling the 74181 for $4.50!!
