Output drive is specified at 15 mA source and 24 mA sink per channel, which is sufficient for driving TTL-level loads on a parallel bus or fanning out to multiple CMOS inputs without external buffers. ## Sourcing and lifecycle — active production, no obsolescence risk For BOM lines that require a through-hole octal buffer with 3-state outputs, this device is a direct fit. No pin-compatible second-source is formally cross-referenced in the TI documentation, but the 74ALS family is widely second-sourced by multiple vendors — confirm the specific order code against your BOM position before committing. ## What the output drive rating means for your bus The 15 mA source / 24 mA sink capability determines how many standard TTL loads the buffer can drive without signal degradation. A single TTL input typically draws 1.6 mA low and 40 µA high, so one SN74ALS541N output can fan out to roughly 15 TTL loads on the low side — enough for a moderate-width address or data bus on a legacy backplane. The 3-state output allows the buffer to be placed in high-impedance mode, enabling multiple devices to share a common bus without contention. This is essential for multiplexed data buses in microprocessor systems or shared peripheral interfaces.","metaTitle":"SN74ALS541N Texas Instruments Buffer, Non-Inverting, 3-State","metaDescription":"SN74ALS541N active-production buffer from TI, 74ALS series, 4.5V to 5.5V supply, 15mA/24mA output drive, 20-DIP through-hole package, RoHS3 compliant.","metaKeywords":null},"attributes":{"series":"74ALS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74ALS","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":"4.5V ~ 5.5V","Number of Elements":"1","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"20-PDIP","Current - Output High, Low":"15mA, 24mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.01","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.01000","currency":"USD"},{"qty":10,"price":"$1.80700","currency":"USD"},{"qty":25,"price":"$1.70440","currency":"USD"},{"qty":100,"price":"$1.45210","currency":"USD"},{"qty":250,"price":"$1.36352","currency":"USD"},{"qty":500,"price":"$1.19306","currency":"USD"},{"qty":1000,"price":"$0.98854","currency":"USD"},{"qty":2500,"price":"$0.92036","currency":"USD"},{"qty":5000,"price":"$0.88628","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6a09b87200d0a9608f6b5a36acce0650.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ALS541N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ALS541N when reusing this data.
