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

The NAND gates in this chip can only pull the output low, so you need something else to pull the output high assuming that you want to see it go high. Also, please give us a proper schematic. So just to be clear, we agree that if both inputs are 1, the output will be 0.

To drive an LED, you need to do something like this: Spehro Pefhany k 4 Post as a guest Name. The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light. I then connect the wires to pin 1 and 2. You will need to add a pull-up resistor to see the output go high. Joe Hass 7, 1 19 It’s a NAND gate. Sign up using Email and Password.

The poor photo of your breadboard is not very helpful. Sign up using Facebook. This should mean that the IC is ON. The 74HCT03 datasheeet open-drain outputs.

I’m using a breadboard as you can see beolow, and no matter what I do, it wont work. This datasheeet what the internal circuit looks like on the 74HC03 from the datasheet.

I migth be stupid, but I can’t really figure this out. Thanks for you answer, and i do know that the picture is silly, i just dunno how to make schematic. You say pullup resistor, 744hc03 i have to connect it from pin 14 or?
