Hi
Im a first year EE student just fooling around with some TTL logic and i cant get my little design to work.
I have a TI SN74LS83AN logic chip "assumed ot be a 4 bit fast adder"
I have a have a data sheet for a Motorolla version and assumed it was the same as i cant find the TI one ANYWHERE
Needless to say the thing doesnt work.
I have built it twice, and tested each part individually as i went, switches, leds powers grounds etc to illiminate any issues later but the thing is still not working and just acts random
Im wondering if the pin out is different
Im new to this so not sure if the pinout would be different or conventionally its the same from manf to manf
Any ideas?
I have a diagram i made in EAGLE if that would be helpful.
Ill post it in a second but for now my question is more about the difference in the datasheet
Thanks
