NAND Gate — UniversalEasyQuestion 20247

Question

NAND gate is called a universal gate because:
  1. A
    It is the most common gate
  2. B
    Any logic function can be implemented using only NAND gates
    Correct
  3. C
    It is the fastest gate
  4. D
    It uses the fewest transistors

Correct answer

Any logic function can be implemented using only NAND gates

Explanation

NAND (and NOR) gates can implement NOT, AND, OR, and any combination → they are functionally complete → any digital circuit can be built using only NANDs (or only NORs). This simplifies manufacturing.
