The exposed pad requires a solder paste stencil aperture covering 50-70% of the pad area to avoid voids and ensure consistent solder joint height. ## Four independent 1:1 bus switches This is a 4-bit bus switch with four independent 1:1 circuits, each controlled by a separate output-enable pin. When the OE pin is low, the switch is on and the signal passes through with low on-state resistance; when high, the switch presents a high-impedance state to isolate the bus segments.","metaTitle":"SN74CBTLV3125RGYR Bus Switch, 4 x 1:1, 14-VQFN","metaDescription":"Texas Instruments SN74CBTLV3125RGYR bus switch, 4 independent 1:1 circuits, 2.3V-3.6V supply, -40°C to 85°C, 14-VQFN package.","metaKeywords":null},"attributes":{"series":"74CBTLV","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Bus Switch","Series":"74CBTLV","Circuit":"1 x 1:1","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"14-VFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"2.3V ~ 3.6V","Independent Circuits":"4","Operating Temperature":"-40°C ~ 85°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"14-VQFN (3.5x3.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.76000","currency":"USD"},{"qty":10,"price":"$0.67200","currency":"USD"},{"qty":25,"price":"$0.63080","currency":"USD"},{"qty":100,"price":"$0.51490","currency":"USD"},{"qty":250,"price":"$0.47828","currency":"USD"},{"qty":500,"price":"$0.40704","currency":"USD"},{"qty":1000,"price":"$0.32563","currency":"USD"},{"qty":3000,"price":"$0.29510","currency":"USD"},{"qty":6000,"price":"$0.28800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2b8eb92bb9ca0cf3096ae5eee15e97f7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the equivalent or alternative parts for SN74CBTLV3125RGYR?","answer":"The 74CBTLV family includes other bus switch configurations, but a direct drop-in replacement from another vendor would require verifying the pinout and electrical characteristics against the TI datasheet."},{"question":"Can SN74CBTLV3125RGYR be used for bidirectional signal switching?","answer":"Yes — the bus switch architecture is bidirectional. When the switch is enabled (OE low), signals pass in either direction between the A and B ports with the same low on-state resistance. This makes it suitable for multiplexing data buses, I2C lines, or GPIO expansion where direction changes during operation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74CBTLV3125RGYR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74CBTLV3125RGYR when reusing this data.
