6.3.2. CMOS NAND Gate Truth Table

Try these first

1. 1.

   What is the output of a NAND gate when both inputs are low?

   Hint

   Think about what the NAND gate does when it has low inputs.

2. 2.

   How many inputs does a traditional NAND gate have?

   Hint

   Recall the definition of a NAND gate.

3. 3.

   What is the output of a NAND gate when both inputs are high?

   • 1
   • 0
   • Depends on the situation

   Hint

   This is specific to how the NAND gate operates.

4. 4.

   True or false: A NAND gate can create every type of other basic logic gate.

   • True
   • False

   Hint

   Think about how you can form other gates from NANDs alone.

5. 5.

   Design a circuit using NAND gates that implements an XOR function. Describe the logic necessary to achieve this.

   Hint

   Think about how one NAND gate can provide the necessary inversion to achieve the XOR behavior.

6. 6.

   Analyze the power consumption in a circuit designed with NAND gates compared to a circuit using AND gates. Discuss the benefits.

   Hint

   Consider the impact of active states in inputs.
