It’s a NAND gate. So just to be clear, we agree that if both inputs are 1, the output will be 0. This chip just won’t work for me. I’m using a breadboard as you can see beolow, and no matter what I do, it wont work.

This should mean that the IC is ON. I then connect the wires to pin 1 and 2.
And a LED to pin 3. I have connected the pins to 10k resistors to ground, so they can be 0 if no power is datasehet. 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. This is what the internal circuit looks like on the 74HC03 from the datasheet.

Home Questions 74hc3 Users Unanswered. I have recently bought this IC: Spehro Pefhany k 4 Also, please give us a proper schematic. The poor photo of your breadboard is not very helpful. Joe Hass 7, 1 dayasheet 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? 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 dtasheet something else to pull the output high assuming that you want to see it satasheet high.
