Topic: Digital Electronics
Minimum number of 2-input NAND gates that will be required to implement the function: $Y=AB+CD+EF$ is
- A. 4
- B. 5
- C. 6
- D. 7
Answer: A. 4
Explanation: $Y=\overline{AB}\cdot\overline{CD}\cdot\overline{EF} = AB+CD+EF$. According to the logic diagram, it requires 4 NAND gates.
