3.3 AHC(T): Advanced High-Speed CMOS
The AHC family provides a natural migration for high speed CMOS (HC) 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, registers, and bus functions that feature higher performance than the HC product family at comparable cost. The AHCT family has the same high speed and low noise capabilities of the AHC family while providing TTL-compatible I/Os when operating from a 5V supply.
