It takes a 3-bit binary input and asserts one of eight active-low outputs — the standard 1 x 3:8 configuration. Output drive is rated 1 mA sourcing and 20 mA sinking. The commercial temperature grade is 0°C to 70°C. The SN74F138N is listed as Active on the lifecycle record and ROHS3 compliant.","metaTitle":"SN74F138N Decoder/Demultiplexer, 1 x 3:8, 16-DIP, Active","metaDescription":"TI SN74F138N 1-of-8 decoder/demultiplexer, 4.5V–5.5V supply, 1mA/20mA output drive, 16-DIP through-hole, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":"74F","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Decoder/Demultiplexer","Series":"74F","Circuit":"1 x 3:8","Package":"Tube","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Independent Circuits":"1","Operating Temperature":"0°C ~ 70°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"16-PDIP","Current - Output High, Low":"1mA, 20mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.62","priceTiers":[{"qty":1,"price":"$0.62000","currency":"USD"},{"qty":10,"price":"$0.54600","currency":"USD"},{"qty":25,"price":"$0.51280","currency":"USD"},{"qty":100,"price":"$0.41840","currency":"USD"},{"qty":250,"price":"$0.38860","currency":"USD"},{"qty":500,"price":"$0.33072","currency":"USD"},{"qty":1000,"price":"$0.26458","currency":"USD"},{"qty":2500,"price":"$0.23977","currency":"USD"},{"qty":5000,"price":"$0.23400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b41f885013406f057e4b3f8ac39f2ade.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74F138N/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN74F138N and SN74LS138N?","answer":"Both are 1-of-8 decoders in 16-DIP, but the 74F family (SN74F138N) typically offers higher speed and lower propagation delay than the 74LS variant. The pinout is the same, so they are functionally interchangeable in most socketed designs — just check the timing budget if the bus runs fast."},{"question":"What is the equivalent of SN74F138N?","answer":"The SN74LS138N is a common functional equivalent in the 74LS family, same 1 x 3:8 decode, same 16-DIP footprint. For a higher-speed alternative, the 74F138 (surface-mount variants) or 74ACT138 are also pin-compatible options."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74F138N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74F138N when reusing this data.
