Question

Which flip-flop is not widely available for commercial purposes?

• A. T flip-flop
• B. SR flip-flop
• C. D flip-flop
• D. JK flip-flop

Hint:

The T flip-flop is mainly used for toggle operations and is less widely available commercially compared to other types.

Answer 1

The Correct Option is A

Step 1: Understanding Flip-flops.
A flip-flop is a bistable circuit used to store binary data. Various types of flip-flops exist, such as SR, D, T, and JK flip-flops, each with unique characteristics.

Step 2: Analysis of options.
- (A) T flip-flop: This flip-flop is not widely used in commercial applications due to its simplicity and limited functionality. It is mainly used in counters.
- (B) SR flip-flop: The SR flip-flop is one of the most common flip-flops used in sequential circuits and available commercially.
- (C) D flip-flop: The D flip-flop is widely used in digital systems for data storage and clock synchronization.
- (D) JK flip-flop: The JK flip-flop is versatile and widely used in various applications like counters, memory units, and more.

Step 3: Conclusion.
The correct answer is (A) T flip-flop, as it is not commonly used in practical applications.
