It accepts TTL input levels while operating at a standard 5 V supply, making it a direct drop-in for 5 V legacy systems that need to interface with CMOS logic. That means no last-time-buy scramble, no forced redesign for a replacement. ## Sourcing and fit for production BOMs For a production BOM that already carries this 74HCT bus transceiver, the active status means supply continuity without redesign.","metaTitle":"MM74HCT640WM Bus Transceiver, 74HCT Series, Active","metaDescription":"Fairchild MM74HCT640WM bus transceiver, 74HCT series, active lifecycle, RoHS non-compliant.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74HCT","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.53","priceTiers":[{"qty":566,"price":"$0.53000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0bde4f8ca7ebdde4a874bbe6940b6794.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MM74HCT640WM/alternatives.json"},"ai":{"faq":[{"question":"What is the function of the MM74HCT640WM?","answer":"It is a bus transceiver from the 74HCT series, used for bidirectional data transfer between two buses in 5 V systems."},{"question":"What are alternatives or equivalents to the MM74HCT640WM?","answer":"For a 5 V-compatible equivalent, look at other 74HCT bus transceivers like the 74HCT245, though pinout and direction control differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MM74HCT640WM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MM74HCT640WM when reusing this data.
