I’m using a breadboard as you can see beolow, and no matter what I do, it wont work. The pullup resistor goes from the NAND gate output pin to the power supply voltage.
I have connected the pins to 10k resistors to ground, so they can be 0 if no power is on. Sign up or log in Sign up using Google. Thanks for you answer, and i do know that the picture is silly, i just dunno how to make schematic.

I then connect the wires to pin 1 and 2. I migth be stupid, but I can’t really figure this out. This is what the internal circuit looks like datasheeet the 74HC03 from the datasheet.
Spehro Pefhany k 4 So just to be clear, we agree that if both inputs are 1, the output will be 0.

It’s a NAND gate. The 74HCT03 has open-drain outputs. Home Questions Tags Users Unanswered. The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light.

This chip just won’t work for me. And a LED to pin 3.
