This chip just won’t work for me.
The poor datasheeg of your breadboard is not very helpful. So just to be clear, we agree that if both inputs are 1, the output will be 0. I have connected the pins to 10k resistors to ground, so they can be 0 if no power is on. Sign up using Facebook. And a LED to pin 3. Post as a guest Name. Sign up or log in Sign up using Google.

It’s a NAND gate.

You say datasehet resistor, do i have to connect it from pin 14 or? I migth be stupid, but I can’t really figure this out. This should mean that the IC is ON. The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light.
I’m using a breadboard as you can datasheeet beolow, and no matter what I do, it wont work. To drive an LED, you need to do something like this: The pullup resistor goes from the NAND gate output pin to the power supply voltage. The 74HCT03 has open-drain outputs. Email Required, but never shown. I then connect the wires to pin 1 and 2. I have recently bought this 74hc30 Joe Hass 7, 1 19 Also, please give us a proper schematic.
You will need to add a pull-up resistor to see the output go high.
