I’m using a breadboard as you can see beolow, and no matter what I do, it wont work.
Spehro Pefhany k 4 I then connect the wires to pin 1 and 2. Email Required, but never shown. Sign up or log 74nc03 Sign up using Google. The poor photo of your breadboard is not very helpful.

Post as a guest Name. This chip just won’t work for me. You say pullup resistor, do i have to connect it from pin 14 or? This is what the internal circuit looks like on the 74HC03 from the datasheet.

Joe Hass 7, 1 19 The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light. I migth be stupid, but I can’t really figure this out. Home Questions Tags Users Unanswered. Sign up using Email and Password.
74HC/HCT03 Quad 2-input NAND Gate
Thanks for you answer, and i do know that the picture is silly, i just dunno how to make schematic. The pullup resistor goes from the NAND gate output pin to the power supply voltage. 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. So just to be clear, we agree daatasheet if both inputs are 1, the output will be 0.

To drive an LED, you need to do something like this: I have recently bought this IC: You will need to add a pull-up resistor to see the output go high. I have connected the pins to 10k resistors to ground, so they can be 0 if no power is on.
