So just to be clear, we agree that if both inputs are 1, the output will be 0.

Post as a guest Name. This chip just won’t work for me. I then connect the wires to pin 1 and 2.

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. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I migth be stupid, but I can’t really figure this out. The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light.

Spehro Pefhany k 4 And a LED to pin 3. Thanks for you answer, and i do know that the picture is silly, i just dunno how to make schematic. It’s a NAND gate. Home Questions Tags Users Unanswered.

The pullup resistor goes from the NAND gate output pin to the power supply voltage.

Email Required, but never shown. You will need to add a pull-up darasheet to see the output go high. I have recently bought this IC: Datashedt is what the internal circuit looks like on the 74HC03 from the datasheet.

I’m using a breadboard as you can see beolow, and no matter what I do, it wont work. The 74HCT03 has open-drain outputs. Also, please give us a proper schematic.
