4-bit parallel adder 74LS283 and 74LS83A

Jan 19, 1. Apr 15, 6. GND is at pin 8 and Vcc at pin I was wondering if the two are functionally same, then what’s the need for two different numbers for the ICs which do the same job.

Perhaps, it is because of the same ICs made by two different manufacturers. What do you think? Please let me know.


Jan 19, 2. Sep 20, 5, 1, Maybe you could try comparing the datasheets. Jan 19, 3.

Thanks for the reply. I don’t have any datasheets neither the ICs. Just was going through a book and read about the ICs.

Jan 20, 6. The only reason I can think of is that back in those ratasheet when the chip was first made some company ordered the chips with this pinout to fit in their deisgn better, and later on the manufacturer made the same chip but this time with connections made in the standard way.
