It selects one of two 4-bit data sources under control of a common select line, routing the chosen nibble to the output. ## Output drive — 400 µA source, 8 mA sink The output high current is rated at 400 µA and output low at 8 mA. That sink current is typical for the 74LS family and drives one standard LS load per output without external buffers. If you are interfacing to a higher-current load (LED, relay coil, or a bus with multiple fan-in), plan on a transistor or a line driver after the mux.","metaTitle":"SN74LS298N Multiplexer, 4 x 2:1, 16-DIP, 74LS Family","metaDescription":"Texas Instruments SN74LS298N multiplexer, 4 x 2:1 circuit, 4.75V to 5.25V supply, 0°C to 70°C, 16-DIP through-hole.","metaKeywords":null},"attributes":{"series":"74LS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Multiplexer","Series":"74LS","Circuit":"4 x 2:1","Package":"Tube","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Independent Circuits":"1","Operating Temperature":"0°C ~ 70°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"16-PDIP","Current - Output High, Low":"400µA, 8mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.45","priceTiers":[{"qty":1,"price":"$2.45000","currency":"USD"},{"qty":10,"price":"$2.19700","currency":"USD"},{"qty":25,"price":"$2.07240","currency":"USD"},{"qty":100,"price":"$1.76560","currency":"USD"},{"qty":250,"price":"$1.65784","currency":"USD"},{"qty":500,"price":"$1.45060","currency":"USD"},{"qty":1000,"price":"$1.20193","currency":"USD"},{"qty":2500,"price":"$1.17300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/39a5bd006bc14431389354d1b0fc2619.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LS298N/alternatives.json"},"ai":{"faq":[{"question":"What is the function of the SN74LS298N?","answer":"The SN74LS298N is a 4-bit, 2-input multiplexer. It selects one of two 4-bit data buses (A or B) based on a common select input and presents the chosen nibble at the output. The part contains one independent multiplexer circuit with four 2:1 channels."},{"question":"What are the alternatives for the SN74LS298N?","answer":"A functional alternative within the same 74LS family is the SN74LS348N, but note that the SN74LS348N is a priority encoder (1 x 8:3), not a multiplexer — it serves a different logic function. For a true multiplexer replacement, look for other 74LS-series 4-bit 2:1 muxes in 16-DIP, such as the 74LS157 or 74LS158, which offer similar pinouts and logic levels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LS298N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LS298N when reusing this data.
