It contains two independent 4-bit elements, each with its own output-enable pin, letting you gate bus segments or drive shared data lines without contention. The 5V supply rail (4.75V–5.25V) and TTL-compatible thresholds mean this part lives in legacy 5V logic systems—not 3.3V or 1.8V domains. Typical applications include memory-address buffering, microprocessor bus isolation, and driving high-fanout clock or control signals where the 24mA sink capability handles multiple TTL loads. ## Temperature grade and operating environment Rated for commercial temperature range 0°C to 70°C (ambient). This is indoor, bench, or office-environment gear—not motor drives, under-hood automotive, or outdoor telecom. If your BOM calls for industrial or extended temperature, you need a 74LS part with an 'I' suffix or a different family entirely. ## Output drive and bus loading With 15mA output high and 24mA output low, the SN74LS241N can sink more current than it sources—typical for TTL. That 24mA sink is enough to drive a 5V TTL bus with multiple loads, but don't expect to charge large capacitive traces quickly. For heavily loaded backplanes or faster edge rates, consider the 74ABT or 74F families. ## Lifecycle and sourcing reality Texas Instruments lists the SN74LS241N as Active. That said, 74LS parts are a mature logic family—production volumes have shrunk and lead times can stretch. The through-hole DIP package also narrows the manufacturing base; most high-volume lines have moved to surface-mount. For new designs, the 74AHCT or 74LVC series in SOIC or TSSOP would be the modern footprint.","metaTitle":"SN74LS241N 74LS Buffer, Non-Inverting, 3-State, 20-DIP","metaDescription":"SN74LS241N is a 74LS octal buffer with 3-state outputs, 5V supply, 0-70°C operation, 20-DIP package.","metaKeywords":null},"attributes":{"series":"74LS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74LS","Package":"Tube","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Number of Elements":"2","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"20-PDIP","Current - Output High, Low":"15mA, 24mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.15","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.15000","currency":"USD"},{"qty":10,"price":"$1.02900","currency":"USD"},{"qty":25,"price":"$0.97640","currency":"USD"},{"qty":100,"price":"$0.80210","currency":"USD"},{"qty":250,"price":"$0.74980","currency":"USD"},{"qty":500,"price":"$0.66260","currency":"USD"},{"qty":1000,"price":"$0.52311","currency":"USD"},{"qty":2500,"price":"$0.49350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/074334bac5ff5b7cfbf08ab2c6ab03e9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the SN74LS241N used for?","answer":"The SN74LS241N is an octal non-inverting buffer with 3-state outputs, used to drive bus lines, buffer address or data signals, and isolate logic sections in 5V TTL systems.
