- Advanced High-Speed CMOS (AHC) Logic Family (Rev. C)PDF, 102 Kb, 修订版: C, 档案已发布: Dec 2, 2002
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-sca
