(note: The 7447 / 74LS47 is the famous BCD to 7 segment decoder IC that everyone should use at least once)
Not sure if this should go here, General Discussion, or Bar Sport, or perhaps nowhere.
I find it sort if interesting that TI still manufactures the 74LS47. This chip was designed around 1974. TI last updated their datasheet for it in 1988. And it’s an active part, you can get it at Digikey. They just won’t sample it to you.
I wonder why this chip needs to continue to be made. Isn’t it available in other families? Is this still used in new designs or just old ones that have been hanging around since I was in high school?
