3.8 HC(T): High-Speed CMOS
The HC family was designed to provide improved switching speed and lower power consumption compared to earlier bipolar logic families. The HCT family has the same capabilities of the HC family while providing TTL-compatible I/Os when operating from a 5V supply for systems that still use some TTL devices. The HC and HCT familes are a staple of digital logic design, providing balanced performance and one of the broadest function sets available today.
