Why Choose SN74HC Series?

• High-Speed CMOS — ~7ns propagation delay, 10× faster than 4000-series CMOS
• TTL-Compatible Inputs — Direct interface with 5V TTL logic without level shifting
• Wide Supply Range — 2V–6V covers 3.3V and 5V systems
• ±25mA Output Drive — Directly drives LEDs, bus lines, and logic inputs
• DIP-14 Package — Breadboard-friendly for prototyping and education

Typical Applications by Variant

• 74HC00/02/03 — Universal logic gates (implement any Boolean function)
• 74HC04/06 — Signal inversion, level conversion, open-drain bus pull-down
• 74HC125 — Bus buffering, 3-state output for shared data buses
• 74HC164 — Serial-to-parallel conversion, LED matrix driving, SPI expansion

FAQ

Q: What’s the difference between 74HC and 74HCT?
A: 74HC has CMOS-level input thresholds (VIH = 0.7×VCC); 74HCT has TTL-level thresholds (VIH = 2.0V fixed). Use 74HCT when interfacing with 5V TTL outputs in a 5V system.

Q: Can 74HC series run at 3.3V?
A: Yes — 74HC operates from 2V–6V. At 3.3V, input thresholds scale accordingly (VIH ≈ 2.3V).
