Experiment 6 - The NAND Gate

In the next three experiments you get to know three more gates. These gates combine an AND, OR, or XOR gate with the NOT gate, and thus negate the result Q. Here you get to know the NAND gate.

The NAND gate results from the combination of an AND and NOT gate. You recognize from the truth table the negated result of an AND gate.

A NAND circuit. (Enlarge)

With the circuit shown, you are able to build a NAND circuit. Again, you only need to replace the IC from Experiment 2 by the C-MOS IC 4011. In the next experiment you negate the OR gate...
