PROJECT 04 – NAND EQUIVALENT CIRCUITS

 

 

OVERVIEW


            In this circuit, you will create a circuit from multiple gates.

DETAILS

If we had just one type of logic gate, we would want it to be the NAND gate because we can create the other basic gates with it. 

 

In the following table, the right column shows the equivalent NAND circuit for the basic logic gate on the left.

BEFORE STARTING

 

Be sure a resistor is placed in series with the LED.

 

Be sure to use a 5V voltage regulator.

 

If the LED doesn’t light up, it might be connected backwards.

 

PART 1 of 1

 

How good are you?

 

Using a NAND chip, recreate one of the basic gates. 

 

·         The NOT gate will get you 50%.

·         The AND gate will get you 70%.

·         The OR gate will get you 80%.

·         The NOR gate will get you 90%.

·         The XOR gate will get you 90%.

·         The XNOR gate will get you a certain 100%.

·         There will also be 10% given for circuit neatness.

 

Have fun!
