The Texas Instruments (TI) advanced high-speed CMOS (AHC) logic family provides a natural migration for high-speed CMOS (HCMOS) users who need more speed for low-power, and low-drive applications. Unlike many other advanced logic families, AHC does not have the drawbacks that come with higher speed, e.g., higher signal noise and power consumption. The AHC logic family consists of gates, medium-scale integrated circuits, and octal functions fabricated using the EPICE process that features higher performance than the HCMOS HC product family at comparable cost.
This application report introduces the AHC logic family characterization information to supplement the AHC/AHCT Logic Advanced High-Speed CMOS Data Book, literature number SCLD003A. The additional information is to aid design engineers in more accurately designing their digital logic systems. The focus is on the family?s features and benefits, product characteristics, and design guidelines. This application report is divided into sections, each dealing with a specific characteristic of the AHC logic family. This application report focuses on the AHC logic family and compares it to the HC family.
