How it works
The setup has two inputs and a signle output. The setup consists of a NOT gate and a NAND gate, where the NOT gate is connected to the first input and feed of one pin of the NAND gate. The second input of the setup is connected to the second input of the NAND gate.
How to test
Send the following signals to IN2 and IN3 to check if the proper NAND output results: INs Out 00 1 10 1 01 0 11 1
External hardware
You can test the chip with with LEDs or other indicators.
