It operates from a 4.5V to 5.5V supply, typical of legacy 5V TTL/CMOS backplanes and industrial control buses. The single-element device handles eight bits per element, with a high-output drive of 32mA sourcing and 64mA sinking—enough to drive heavily loaded parallel lines without external line drivers. ## 32mA/64mA drive — what it means for the bus The output drive of 32mA high and 64mA low is the headline selection parameter. It lets the buffer fan out to multiple CMOS inputs (typically 10–15 loads at 5V) while maintaining clean logic levels. Compared to the 74AHCT540 inverter buffer (8mA symmetric drive), the SN74ABT541BNSR delivers roughly 4× the low-side current, which matters when driving a shared data bus with long trace capacitance or multiple transceivers. ## Industrial temperature and ROHS3 compliance Rated for -40°C to 85°C ambient, the SN74ABT541BNSR fits industrial control cabinets, outdoor telecom equipment, and factory-floor I/O modules. The ROHS3 compliance means no lead-free reflow compatibility concerns—standard Pb-free soldering profiles apply. The part is listed as Active, so no end-of-life risk for ongoing production. ## Package and assembly Housed in a 20-SOIC with 5.30mm body width, the narrow SOIC footprint matches common 20-pin land patterns. The tape-and-reel option supports automated pick-and-place. Surface-mount assembly with standard MSL 3 handling applies—bake before reflow if the moisture barrier bag has been open past the floor-life window.","metaTitle":"SN74ABT541BNSR 74ABT Buffer, Non-Inverting, 3-State, 20-SOIC","metaDescription":"TI SN74ABT541BNSR 74ABT octal buffer, 4.5V–5.5V supply, 32mA/64mA drive, industrial temp -40°C to 85°C, ROHS3, active.","metaKeywords":null},"attributes":{"series":"74ABT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74ABT","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-SO","Current - Output High, Low":"32mA, 64mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.35","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.35000","currency":"USD"},{"qty":10,"price":"$1.20400","currency":"USD"},{"qty":25,"price":"$1.14280","currency":"USD"},{"qty":100,"price":"$0.93860","currency":"USD"},{"qty":250,"price":"$0.87740","currency":"USD"},{"qty":500,"price":"$0.77540","currency":"USD"},{"qty":1000,"price":"$0.61215","currency":"USD"},{"qty":2000,"price":"$0.57750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e989fde828b7847f5620078d7b3245ff.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74ABT541BNSR RoHS compliant?","answer":"Yes, the SN74ABT541BNSR is ROHS3 compliant, meaning it meets the EU RoHS directive for lead-free and restricted substances."},{"question":"Can SN74ABT541BNSR replace SN74ABT541BN?","answer":"The SN74ABT541BNSR is the surface-mount (SOIC) variant of the SN74ABT541BN, which is the DIP version.
