Hello,
Noob question..
I have a problem here trying to test a few K155ID1's that I've came across but i just don't get how they work.
Ive tried using this simple schematics to test it out but no luck. Can someone tell me what I'm doing wrong.
So when you look at the truth table if all 4 inputs are low (0v?) output "0" shoud be on turning IN-14 bulb on right? I mean the gate should open letting the common ground to pass the IC and turn on the lamp. Or im totally off here
even when i try different combinations relaying 5v to inputs accordingly it just doesnt work.
Here's the scematics im trying to do.
