Question

The circuits of NOR-based S-R latch are classified as asynchronous sequential circuits, why?

• A. Because of inverted outputs
• B. Because of triggering functionality
• C. Because of cross-coupled connection
• D. Because of inverted outputs & triggering functionality

Hint:

The cross-coupled connection in NOR-based latches makes them asynchronous as the output can change based on the current input, without relying on a clock signal.

Answer 1

The Correct Option is C

NOR-based S-R latches are asynchronous sequential circuits because they use a cross-coupled connection between the inputs and outputs, which allows the output to change independently of the clock signal. Thus, the correct answer is Because of cross-coupled connection.
