Sign up using Email and Password. 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. Email Required, but adtasheet shown.
The pullup resistor goes from the NAND gate output pin to the power supply voltage. This is what the internal circuit looks like on the 74HC03 from the datasheet.

I then connect the wires to pin 1 and 2. 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 should mean that the IC is ON.

I have recently bought this IC: To drive an LED, you need to do something like this: The poor photo of your breadboard is not very helpful.
The 74HCT03 has open-drain outputs.
Post as a guest Name. Home Questions Tags Users Unanswered. So just 74gc03 be clear, we agree that if both inputs are 1, the output will be 0.
And a LED to pin 3. Sign up using Facebook. Joe Hass 7, 1 19 Sign up or log in Sign up using Google. I’m using a 74hc0 as you can see beolow, and no matter what I do, it wont work. You will need to add a pull-up resistor to see the output go high.
You say pullup resistor, do i have to connect it from pin 14 or? Spehro Pefhany k 4 It’s a NAND gate. This chip just won’t work for me. Also, please give us a proper schematic.
