This is what the internal circuit looks like on the 74HC03 from the datasheet. I then connect the wires to pin 1 and 2. You will need to add a pull-up resistor to see the output go high.

Spehro Pefhany k 4 I’m using dataasheet breadboard as you can see beolow, and no matter what I do, it wont work. Post as a guest Name.

This chip just won’t work for me. Home Questions Tags Users Unanswered. So just to be clear, we agree that if both inputs are 1, the output will be 0.

And a LED datasheey pin 3. Also, please give us a proper schematic. I datashwet connected the pins to 10k resistors to ground, so they can be 0 if no power is on. Sign up using Facebook.

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? This should mean that the IC is ON.
