High-Speed CMOS 74HCxxx Series IC 74HC27 74HC32 74HC51 74HC113 74HC242 74HC243 74HC280 (DIP-14)

• The 74HCxxx series is a family of high-speed complementary metal-oxide semiconductor (CMOS) integrated circuits (ICs) that are part of the 7400 series. The 74HC00 family is an improvement on the 74C00 series, which was an alternative to the 4000 series.

• These ICs are known for their fast operation and reliable performance, making them suitable for a wide range of digital circuit applications. HCMOS (“high-speed CMOS”) is the set of specifications for electrical ratings and characteristics, forming the 74HC00 family, a part of the 7400 series of integrated circuits.
