Question

What is the difference between a 7400 and a 7411 IC?

The correct answer is

7400 has four two-input NAND gates; 7411 has three three-input AND gates

Therefore, the 7411 chip provides three independent 3-input AND gates. In simple terms, the 7400 provides more gates (four vs three) but they are simpler (2-input NAND), while the 7411 provides fewer gates (three vs four) but they are more complex (3-input AND). Therefore, the correct answer is 7400 has four two-input NAND gates; 7411 has three three-input AND gates.
