The term that denotes how many standard logic inputs can be driven by a single gate output without exceeding the gate’s rated source/sink currents is called ________.

Introduction / Context:
When interconnecting logic gates, one output often feeds multiple inputs. The allowable number of such inputs is limited by current and voltage specifications. This limit is formalized with a specific term.

Given Data / Assumptions:

• One gate output drives several standard inputs.
• The limit is determined by I_OH/I_OL and input currents I_IH/I_IL.
• We seek the formal term for this limit.

Concept / Approach:
Fan-out = allowable number of standard inputs that a single output can drive while still meeting V_OH and V_OL guarantees. For TTL, fan-out is often asymmetric because sinking capability is higher than sourcing. Exceeding fan-out risks slow edges and invalid logic levels.

Step-by-Step Solution:
Identify the metric: number of inputs per output.Match to the standard term: fan-out.Relate to datasheet currents: fan-out ≈ I_OL/I_IL (for LOW) and I_OH/I_IH (for HIGH).

Verification / Alternative check:
Datasheets sometimes state fan-out directly or provide the currents to calculate it.

Why Other Options Are Wrong:
Propagation relates to delay; dissipation is power; SSI classifies integration scale (small-scale integration); noise margin is voltage headroom against noise.

Common Pitfalls:
Ignoring differing HIGH vs LOW drive limits; the smaller of the two determines practical fan-out.

Final Answer:
fan-out
