Mouser pass the SN7404 test

SN74LS
https://www.mouser.co.uk/c/?q=sn74ls&instock=y&normallystocked=y brings up
381 lines in stock; doubtless lots of package / packaging duplicates
DS8641 (Q/U bus transceiver) and suchlike are of course quite another story :
substantially unobtanium

Standard TTL 74XXX is drying up rather quickly.
Futurlec still has
some TTL but 7404s are all gone. Even LS is hard to find.
Ours comes from Mouser, between two part #s they have over 7,000 74LS04s in DIP packaging
in stock. Didn't check ACT, HCT, or ALS. I don't think we've had a 7400 series
part that we couldn't just order off Mouser in recent history, and we're usually
buying QTY 100.
Thanks,
Jonathan
