The poor photo of your breadboard is not very helpful. The funny thing is that whenever I disconnect the wire that goes from pin datasheeg to ground, the LED starts to light. Sign up using Facebook. This is what the internal circuit looks like on the 74HC03 from the datasheet.

To drive an LED, you need to do something like this: Spehro Pefhany k 4 Sign up using Email and Password. The pullup resistor goes from the NAND gate output pin to the power supply datsheet. 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.

This chip just won’t work for me. I have connected the pins to 10k resistors to ground, so they can be 0 if no power is on. Joe Hass 7, 1 19 Also, please give us a proper schematic.

I have recently bought this IC: It’s a NAND gate.

I migth be stupid, but I can’t really figure this out. So just to be clear, we agree that if both inputs are 1, the output will be datxsheet.

Thanks for you answer, and i do know that the picture is silly, i just dunno how to make schematic. You say pullup resistor, do i have to connect it from pin 14 or? I then connect the wires to pin 1 and 2.
