This is an interesting thread, not least because I haven’t used any traditionally based logic in any of my designs for some years, and the last time was for simple level translation.
I was brought up in the 70s on 74 series TTL (straight up, none of this LS nonsense), and even some DTL, and still maintain a pretty reasonable selection of more modern variations in stock particularly in little logic versions in LVC, AUC and AUP, which are used for one-offs and jigs, but in commercial products I invariably end up engineering them out nowadays.
Which is a shame, as they hold sentimental value, they are a major part of my EE career.
In those days, just like the modern day Windows vs Linux and PIC vs Atmel culture wars, there was a minor TTL vs CMOS war going on, based around the perceived fragility of 4000 series compared to the power hogging but faster TTL. Of course the benefit of hindsight is that you used the best to fit the bill, based on a multitude of functional and non-functional requirements, and available skills. Plus ca change.
Edit: when I was 14, I won a school book prize. ISTR the budget was about £5-£10. I chose the TTL Data Book. I am sure that tome has been on the bookshelves of many thousands of engineers, and TI still lives off its reputation, and usually these days still deserves it.
