TTL AND gate
Électronique / Electronic

Did you figure out how to make an AND gate using the NAND gates?

Hope so, and now we'll see how right you were. Leave the Select Switch at B as you build this circuit.

When you've finished, put the power ON. Press the Key. What does LED 1 do?

Now set the Select Switch to A while pressing the Key. Is there any change in LED 1?

As you saw, pressing the Key and setting the Select Switch to A are 1 inputs, causing a 1 output from the AND gate. Can you follow the 1 input through the circuit until you reach a 1 output? Try it. and don't peek at the answer.
