I have recently bought this IC: You will need to add a pull-up resistor to see the output go high. 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. Joe Hass 7, 1 19 This should mean that the 74h0c3 is ON. To drive an LED, you need to do something like this: Email Required, but never shown.

I’m using a breadboard as you can see beolow, and no matter what I do, it wont work. The pullup resistor goes from the NAND gate output pin to the power supply voltage.

I have connected the pins to 10k resistors to ground, so they can be 0 if no power is on. Sign up or log in Sign up using Google. Thanks for you answer, and i do know that the picture is silly, i just dunno how to make schematic.

I then connect the wires to pin 1 and 2. I migth be stupid, but I can’t really figure this out. This is what the internal circuit looks like datasheeet the 74HC03 from the datasheet.

Spehro Pefhany k 4 So just to be clear, we agree that if both inputs are 1, the output will be 0.

It’s a NAND gate. The 74HCT03 has open-drain outputs. Home Questions Tags Users Unanswered. The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light.

This chip just won’t work for me. And a LED to pin 3.
