I have connected the pins to 10k resistors to ground, so they can be 0 if no power is on. To drive an LED, you need to do something like this: Thanks for you answer, and i do know that the picture is silly, i just dunno how to make schematic. Post as a guest Name.
This is what the internal circuit looks like on the 74HC03 from the datasheet. You will need to add a pull-up resistor to see the output go high. I then connect the wires to pin 1 and 2.
This should mean that the IC is ON. This chip just won’t work for me. You say pullup resistor, do i have to connect it from pin 14 or? I migth be stupid, but I can’t really figure this out.

The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light. Email Required, but never shown. The poor photo of your breadboard is not very helpful.

I’m using a breadboard as you can see beolow, and no matter what I do, it wont work. 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.
And a LED to pin 3. It’s a NAND gate.
74HC/HCT03 Quad 2-input NAND Gate
The pullup resistor goes from the NAND gate output pin to the power supply voltage. I have recently bought this IC: Home Questions Tags Users Unanswered. So just to be clear, we agree that if both inputs are 1, the output will be 0.
