are those giant through hole ICs that do nothing but a very basic task (nand gate, multiplexer, etc) used in industry at all? or are they just made for hobbyists and education?
@SuricrasiaOnline Does anything that Texas Instruments makes have a purpose beyond academia/hobbyists?
@violet @SuricrasiaOnline they make lots and lots of MCUs, DSPs, and adjacent components which see heavy use in industry, but the through-hole stuff is basically all for hobbyist use, maybe prototyping but we doubt it, and we suspect also repairing old systems which remain in use rather than being replaced
@SuricrasiaOnline 7400 series buffers, inverters, and shift registers show up sometimes for dealing with io but overall the family isn't _that_ common anymore
@SuricrasiaOnline yes, sometimes you do see one or two errant 74LSxx chips on a board. Increasingly rare though
@SuricrasiaOnline I use the surface mount versions all the time for little glue logic. I don't think the chunky through hole versions are used for anything but academia, prototyping, and replicating OLLLLLDDD stuff
@SuricrasiaOnline They used to be used in industry all over the place as "glue logic"; lots of times you really just do need A NAND Gate for something. These days I think the surface-mount versions are much more popular in industry, but I'm pretty sure the 7400 through-hole chips must still be used for something, because lord knows the electronics hobbyist industry isn't big enough to support them alone.
