What type of logic levels are compatible with the input characteristics of the 8086microprocessor?A. TTLB. CMOSC. Both A and BD. Neither A nor B

1. Break Down the Problem

To determine the compatible logic levels for the input characteristics of the 8086 microprocessor, we need to understand what TTL and CMOS are, as well as the logic levels used by the 8086.

2. Relevant Concepts

• TTL (Transistor-Transistor Logic): A type of digital logic design that employs bipolar junction transistors. Logic high (1) is typically around 2.0V to 5.0V, while logic low (0) is from 0V to 0.8V.
• CMOS (Complementary Metal-Oxide-Semiconductor): A type of technology for constructing integrated circuits. For CMOS, logic high is usually 3.5V to 5V, and logic low is typically close to 0V.
• 8086 Microprocessor Input Characteristics: The 8086 has input thresholds that are compatible with TTL logic levels.

3. Analysis and Detail

The 8086 can interpret both TTL and CMOS logic levels. However, since it primarily adheres to TTL levels, the fundamental compatibility means that it can work with standard TTL outputs. In practical applications, many CMOS devices are designed to be compatible with TTL logic, enabling their use with the 8086 as well.

4. Verify and Summarize

Given that the 8086 can interface with TTL logic and can also read certain CMOS signals, the most accurate statement regarding its compatibility is that it works with both logic levels.

Final Answer

C. Both A and B
