What is a significant property of a bistable circuit?

A bistable circuit is defined by its ability to maintain one of two stable states indefinitely without the need for continuous power. This characteristic allows the circuit to remember its state even when not powered, making it fundamental in digital electronics, such as in flip-flops and memory storage devices. The bistable nature means that it can switch between these two states based on input signals, but once the state is set, it will remain that way until changed by an external trigger.

In contrast, a configuration with only one stable state would not qualify as bistable, since it would not have an alternative state to switch to. The function of time delays pertains more to monostable circuits rather than bistable, which specifically focuses on maintaining states rather than timing. Furthermore, the notion that a bistable circuit requires constant power is inaccurate; it only requires power when switching states but can retain its last state without needing ongoing power.
