And a LED to pin 3. Sign up using Facebook. The poor photo of your breadboard is not very helpful.
I migth be stupid, but I can’t really figure this datwsheet. Email Required, but never shown. This chip just won’t work for me. The NAND gates in this chip can only pull the output low, so you need something else to pull the datashete high assuming that you want to see it go high. The pullup resistor goes from the NAND gate output pin to the power supply voltage.
The 74HCT03 has open-drain outputs. So just to be clear, we agree that if both inputs are 1, the output will be 0.

This 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.
This should mean that the IC is ON. I then connect the wires to pin 1 and 2.
You say pullup resistor, do i have to connect it from pin 14 or? Joe Hass 7, 1 19 Spehro Pefhany k 4 The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light.
