If both inputs are provided simultaneously to an RS latch flip-flop, what is the result?

In the context of an RS latch flip-flop, when both inputs are provided simultaneously—meaning both the Set and Reset inputs are activated—it creates a situation referred to as an "illegal state." This condition leads to toggling behavior, where the outputs do not settle into a stable state. Instead, the outputs may fluctuate between high and low states, as the conflicting signals attempt to dictate the output simultaneously.

The RS latch is designed to maintain a stable output based on one active input at a time. When both inputs are high, the latch has no defined output, resulting in this toggling effect rather than yielding a definitive high or low output. Thus, the RS latch enters this indeterminate state when both inputs are asserted, illustrating the significance of proper input management in digital electronics.

Understanding this behavior is crucial when designing circuits involving flip-flops, as it highlights the importance of avoiding simultaneous activation of both Set and Reset inputs.
