Understanding the 2-Input OR Gate
An OR gate is a fundamental digital logic gate that performs a logical disjunction. It takes two binary inputs and produces a single output.
Functionality of the OR Gate
- The output of the OR gate is defined as follows:
- If at least one input is 1, the output is 1.
- The output is 0 only if both inputs are 0.
Truth Table for a 2-Input OR Gate
- Here’s a simple truth table that illustrates the behavior of a 2-input OR gate:
Explanation of the Correct Answer
- Therefore, the only condition where the output of a 2-input OR gate is zero occurs when:
- Both inputs are 0 (Input A = 0, Input B = 0).
Conclusion
- Hence, the correct answer is option 'A'. This characteristic is essential for understanding basic digital circuits and logic operations. The OR gate is widely used in various applications, including arithmetic operations and decision-making circuits.

Truth Table for a 2-Input OR Gate
- Here’s a simple truth table that illustrates the behavior of a 2-input OR gate:
- Input A: 0, Input B: 0 → Output: 0
- Input A: 0, Input B: 1 → Output: 1
- Input A: 1, Input B: 0 → Output: 1
- Input A: 1, Input B: 1 → Output: 1
Explanation of the Correct Answer
- Therefore, the only condition where the output of a 2-input OR gate is zero occurs when:
- Both inputs are 0 (Input A = 0, Input B = 0).
Conclusion
- Hence, the correct answer is option 'A'. This characteristic is essential for understanding basic digital circuits and logic operations. The OR gate is widely used in various applications, including arithmetic operations and decision-making circuits.
