Key Concepts
- -- Logic Family
- A group of digital circuits fabricated using the same technology, exhibiting compatible electrical characteristics.
- -- Propagation Delay
- The time it takes for a change in input to be reflected at the output, critical in assessing circuit speed.
- -- Noise Margin
- The tolerance of a logic family to variations in input signals without causing erroneous outputs.
- -- Power Dissipation
- The amount of power consumed by a logic family during operation, vital for thermal management.
