Multivibrator taxonomy — Evaluate the claim: “The bistable multivibrator is an R–C flip-flop.” Distinguish from monostable and astable types.

Introduction / Context:
Multivibrators are classified as astable (oscillator), monostable (one-shot), and bistable (flip-flop). Only the astable and monostable rely inherently on R–C timing networks to create a time constant. A bistable has two stable states and no inherent timing component; it remains in a state until triggered to change.

Given Data / Assumptions:

• Bistable multivibrator = flip-flop with two stable equilibria.
• Astable and monostable use R–C to generate timing (period or pulse width).
• Technology may be discrete, TTL, or CMOS; definitions do not change.

Concept / Approach:
The hallmark of an R–C-based multivibrator is a timing interval determined by the product R*C (e.g., T ≈ 0.693 * R * C in common configurations). Bistables do not require such timing; they change state only upon an input trigger and then remain indefinitely. Therefore, calling a bistable an “R–C flip-flop” is inaccurate; it is a cross-coupled latch/flip-flop, not a timing circuit.
