Also, please give us a proper schematic. I then connect the wires to pin 1 and 2.

Spehro Pefhany k 4 The Datashedt 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.

Post as a guest Name. You say pullup resistor, do i have to connect it from pin 14 or?

Email Required, but never shown. The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light.
The pullup resistor goes from the NAND gate output pin to the power supply voltage. You will need to add a pull-up resistor to see the output go high. I have connected the pins to 10k resistors to ground, so they can be 0 if no power is on.
Thanks for you answer, and i do know that the picture is silly, i just dunno how to make schematic. To drive an LED, you need to do something like this: I have recently bought this IC: So just to be clear, we agree that if both inputs are 1, the output will be 0.
