Hello All,
It's been 10+ years and since playing with logic IC's and I have a project that needs some logic for model railway signals. I have 2 input relays and 4 common anode led's to light according to the input from the switch relays. I made a diagram with a truth table. What 7400 series chips should I use?
ps. I could easily do this with a micro-controller but i have tons of IC chips around from the digital electronic days in Grade school.
