Break Down the Problem

1. We need to determine the number of address lines needed for a multiplexer with 500 information inputs.

Relevant Concepts

2. The number of address lines $n$ for a multiplexer can be calculated using the formula: $2^n \geq N$ where $N$ is the number of inputs.

Analysis and Detail

3. Let's apply the formula to find $n$:

   • We need to find the smallest $n$ such that: $2^n \geq 500$
   • We will calculate the powers of 2:
     • $2^8 = 256$ (not sufficient)
     • $2^9 = 512$ (sufficient)

   Therefore, $n = 9$ is the smallest number satisfying the condition.

Verify and Summarize

4. We have verified that $2^9 = 512$ can accommodate 500 inputs, while $2^8 = 256$ cannot. Thus, the correct answer is 9 address lines.

Final Answer

The number of address lines for the multiplexer is 9 (F).
