74HC/HCT03 Quad 2-input NAND Gate

The poor photo of your breadboard is not very helpful. The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light. This should mean that the IC is ON. This is what the internal circuit looks like on the 74HC03 from the datasheet.

You will need to add a pull-up resistor to see the output go high. Joe Hass 7, 1 19 Sign up using Facebook. 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 74hc0.

It’s a NAND gate.

I have connected the pins to datashret resistors to ground, so they can be 0 if no power is on. The pullup resistor goes from the NAND gate output pin to the power supply voltage. I then connect the wires to pin 1 and 2. Spehro Pefhany k 4 The 74HCT03 has open-drain outputs. Post as a guest Name.

I’m using a breadboard as you can see beolow, and no matter what I do, it wont work. So just to be clear, we agree that if both inputs are 1, the output will be 0.
