High-Speed CMOS 74HCxxx Series IC 74HC42 74HC109 74HC133 74HC137 74HC138 (DIP-16)

• 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.
