Digital IC packaging terminology: The phrase “hex inverter” most commonly refers to which device configuration?

Introduction / Context:
IC datasheets and catalogs often describe logic packages with counts like “dual,” “quad,” and “hex.” Understanding this shorthand helps engineers pick appropriate parts and pinouts without confusion during schematic capture and PCB layout.

Given Data / Assumptions:

• “Hex” denotes the number six.
• We are considering inverter (NOT) gates packaged together in one IC.
• Common logic families (TTL, CMOS) offer standard hex inverter parts (e.g., 7404/74HC04).

Concept / Approach:
A “hex inverter” is an IC containing six independent inverter gates, each with one input and one output, all sharing power pins. The device provides multiple identical functions in one package to save board area and routing complexity.

Step-by-Step Reasoning:
Interpret “hex” as six.Associate with inverter function (NOT gate).Conclude: the package contains six separate inverters.

Verification / Alternative check:
Review a standard part like 74HC04: the pinout shows six inverter sections labeled A–F. Each section operates independently within the same IC.

Why Other Options Are Wrong:

• “An inverter that has six inputs” describes a multi-input gate, not a hex package.
• “A six-input symbolic logic device” is vague and not standard terminology.
• “A history of failure” misinterprets “hex” humorously; it is unrelated to reliability.

Common Pitfalls:

• Confusing “hex” (six functions) with “six-input”; they are different concepts.
• Overlooking that some packages mix functions (e.g., Schmitt-trigger inverters) but still count as hex.

Final Answer:
six inverters in a single package
