That flexibility saves a dedicated level-translator IC when mixing voltage domains on a mixed-signal board or a legacy bus interface. ## Output drive — 16 mA sink and source Each output is rated for 16 mA source and 16 mA sink at the rated supply voltage. This is enough to drive a handful of CMOS logic inputs, an LED indicator, or a short PCB trace without an external buffer. Budget the total package current — 8 outputs × 16 mA = 128 mA theoretical max — against the package's thermal limits in the 20-SOIC at 125°C ambient. ## Package and assembly — 20-SOIC on Tape & Reel The 20-SOIC footprint is a standard JEDEC outline — no exotic land pattern required.","metaTitle":"SN74LV540ANSR Buffer, Inverting 3-State 20-SOIC","metaDescription":"Texas Instruments SN74LV540ANSR 74LV series inverting buffer with 3-state outputs, 2V-5.5V supply, 16mA drive, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"74LV","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74LV","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Buffer, Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 5.5V","Number of Elements":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"20-SO","Current - Output High, Low":"16mA, 16mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.08","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.08000","currency":"USD"},{"qty":10,"price":"$0.96600","currency":"USD"},{"qty":25,"price":"$0.91720","currency":"USD"},{"qty":100,"price":"$0.75330","currency":"USD"},{"qty":250,"price":"$0.70420","currency":"USD"},{"qty":500,"price":"$0.62232","currency":"USD"},{"qty":1000,"price":"$0.49131","currency":"USD"},{"qty":2000,"price":"$0.46350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/561e0b9c7ffbaf94c2047b92fdf7c425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74LV540ANSR a direct replacement for SN74LV540ADWR?","answer":"The SN74LV540ADWR is the same 74LV inverting buffer in a 20-SOIC package, but with a different tape-and-reel suffix (DWR vs NSR). The two parts are functionally identical — same logic, same supply range, same temperature grade, same package outline. The difference is the reel quantity and the reel orientation (embossed vs standard). For a BOM line, they are drop-in replacements as long as the pick-and-place feeder setup is verified for the reel format."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LV540ANSR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LV540ANSR when reusing this data.
