Logic gates and inverters are the fundamental building blocks of digital circuits — performing AND, OR, NAND, NOR, XOR, and NOT operations in applications such as glue logic, level conversion, signal routing, and clock buffering. Our selection spans classic 74-series logic families, including 74HC, 74HCT, 74LVC, 74AHC, 74AHCT, and 74AC/ACT from Texas Instruments, NXP Semiconductors, ON Semiconductor, and Toshiba, in DIP-14, SOIC-14, SSOP, TSSOP, and SC-70 packages — covering single gates (SOT-23), dual, triple, quad, and hex configurations.
DIP-package logic ICs (74HC00, 74HC04, 74LS series) remain in high demand for educational, hobbyist, and repair markets, while TSSOP and SC-70 versions serve high-density SMD production. Welllinkchips stocks both current and obsolete 74-series part numbers, including legacy 4000-series CMOS and discontinued bipolar TTL devices for legacy board repair.
