The 16-DIP (0.300\", 7.62 mm) through-hole footprint is a standard on legacy control boards and retrofit cards. ## Production status and sourcing posture The SN74HCT139N is listed as Active, with a ROHS3 compliance level. No end-of-life notice or last-time-buy window has been issued. For volume production or a BOM line that needs this exact decoder, we can quote against an RFQ with current availability and pricing confirmed at quote time.","metaTitle":"SN74HCT139N Decoder/Demultiplexer, 1 x 2:4, 16-DIP, Active","metaDescription":"SN74HCT139N is a 74HCT dual 2:4 decoder/demultiplexer in 16-DIP. 4.5–5.5 V supply, -40 to 85°C range, 4 mA output drive.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Decoder/Demultiplexer","Series":"74HCT","Circuit":"1 x 2:4","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":"2","Operating Temperature":"-40°C ~ 85°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"16-PDIP","Current - Output High, Low":"4mA, 4mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.78","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.78000","currency":"USD"},{"qty":10,"price":"$0.68600","currency":"USD"},{"qty":25,"price":"$0.64400","currency":"USD"},{"qty":100,"price":"$0.52560","currency":"USD"},{"qty":250,"price":"$0.48824","currency":"USD"},{"qty":500,"price":"$0.41552","currency":"USD"},{"qty":1000,"price":"$0.33242","currency":"USD"},{"qty":2500,"price":"$0.30125","currency":"USD"},{"qty":5000,"price":"$0.29400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e7f8becf6ccdad9279f902d170c5e2d0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can SN74HCT139N replace 74LS139?","answer":"Yes, the SN74HCT139N is pin-compatible with the 74LS139 and runs on the same 5 V supply. The HCT family has TTL-compatible inputs, so it drops directly into a 74LS139 socket. The main difference is lower power consumption (CMOS) and slightly different input thresholds — verify with the datasheet if the old design relied on LS-specific noise margins."},{"question":"Is SN74HCT139N equivalent to 74HCT139?","answer":"Yes, SN74HCT139N is the Texas Instruments ordering code for a standard 74HCT139 in a 16-pin DIP package. The 'SN' prefix is TI's own code; the core device is the industry-standard 74HCT139 dual 2:4 decoder/demultiplexer."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74HCT139N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74HCT139N when reusing this data.
