I checked mouser (canada) again. After about 3 pages of garbage matches,
I found some 7904's in DIP packages, only a few 100 in stock.
TI and Motorola sell 74LS541's but only the Motorola part has Vin Low of
.8 volts. TI has .6 Vin low. Are there any more part differences between
TI and other digital logic.
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,
