It provides four independent three-state buffer stages, each with its own output-enable control, designed for driving bus lines or buffering address/data paths in 5 V logic systems. This part targets general-purpose digital designs in industrial control, test equipment, and legacy 5 V TTL backplanes where fan-out and noise margin matter more than speed. For high-volume pick-and-place, verify that your feeder setup can handle tube-fed parts, or check whether a tape-and-reel option exists under a different ordering suffix.","metaTitle":"74LS126SC Fairchild 4-Bit Bus Driver, TTL, Active","metaDescription":"74LS126SC is an active Fairchild 4-bit bus driver from the 74LS TTL family.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.17","stockQuantity":0,"priceTiers":[{"qty":2217,"price":"$0.17000","currency":"USD"}]},"links":{"datasheetUrl":"https://rocelec.widen.net/view/pdf/gyxg8s8kdz/FAIRS32135-1.pdf?t.download=true&u=5oefqw","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74LS126SC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74LS126SC when reusing this data.
