Terminology check: another name for a one-shot multivibrator Which term is equivalent to a one-shot circuit?

Introduction / Context:
Timing circuits are often categorized by how many stable states they possess. A one-shot produces a single, time-controlled pulse when triggered and then returns to its stable state. Recognizing the alternate names helps when reading datasheets and textbooks across different regions and eras.

Given Data / Assumptions:

• A “one-shot” has exactly one stable state and one quasi-stable state.
• The circuit requires a trigger to initiate the output pulse.
• After a set time, it returns to the stable state without further input.

Concept / Approach:

“Monostable” literally means one stable state. Triggering causes a temporary excursion to a quasi-stable state for a defined interval (set by RC or other timing elements). When the interval ends, the circuit relaxes back to its stable state. 555 timers in monostable mode are a common implementation.

Step-by-Step Explanation:

Verification / Alternative check:

Oscilloscope observation shows one output pulse per valid trigger; no oscillation occurs without repeated triggers.

Why Other Options Are Wrong:

• Bistable: two stable states (flip-flop).
• Astable: no stable state (free-running oscillator).
• Tristable/multistable: terms not used for one-shot timing behavior.

Common Pitfalls:

• Confusing one-shot with retriggerable monostable; retriggering extends the pulse width.
• Assuming a one-shot will repeat without new triggers; it will not.

Final Answer:

monostable
