Housed in the compact SM8 package (8-LSSOP or 8-MSOP, 2.80mm body width), it suits space-constrained layouts in industrial control, sensor interfaces, and general-purpose address decoding. The 1.65V to 5.5V supply range covers the common 1.8V, 2.5V, and 3.3V rails, and stretches to 5V for legacy TTL-compatible designs. If your design lives in a conditioned server room, the commercial-grade sibling (0°C to 70°C) may save a few cents, but the SN74LVC1G139DCTT covers both environments without a qualification change. The ROHS3 compliance is current and covers global shipping requirements. ## Package and footprint — SM8 (8-LSSOP / 8-MSOP) The SM8 package (supplier device package code) is a 0.110-inch-wide, 2.80mm-body 8-lead SSOP or MSOP. The 0.65mm pin pitch is standard for fine-pitch SOP footprints, and the body is small enough to fit under a 0.5W resistor. No thermal pad is needed; the package dissipates through the leads. If your layout already uses 8-MSOP for op-amps or level translators, this part drops in with no board change.","metaTitle":"SN74LVC1G139DCTT TI 74LVC Decoder/Demux 1x2:4, 1.65-5.5V","metaDescription":"Texas Instruments SN74LVC1G139DCTT 74LVC single 2:4 decoder/demultiplexer, 1.65V-5.5V supply, 32mA output, -40 to 85°C, SM8 package.","metaKeywords":null},"attributes":{"series":"74LVC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"Decoder/Demultiplexer","Series":"74LVC","Circuit":"1 x 2:4","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"8-LSSOP, 8-MSOP (0.110\\\", 2.80mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"1.65V ~ 5.5V","Base Product Number":"74LVC1G139","Independent Circuits":"1","Operating Temperature":"-40°C~85°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"SM8","Current - Output High, Low":"32mA, 32mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3800","priceTiers":[{"qty":1,"price":"$1.38000","currency":"USD"},{"qty":10,"price":"$1.23500","currency":"USD"},{"qty":25,"price":"$1.17240","currency":"USD"},{"qty":100,"price":"$0.96300","currency":"USD"},{"qty":250,"price":"$0.90020","currency":"USD"},{"qty":500,"price":"$0.79552","currency":"USD"},{"qty":1250,"price":"$0.62805","currency":"USD"},{"qty":2500,"price":"$0.59250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6cc793520daa34aceba2c4858aa140fe.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVC1G139DCTT/alternatives.json"},"ai":{"faq":[{"question":"What is a replacement or alternative for SN74LVC1G139DCTT?","answer":"The SN74LVC1G139DCTT is a single 2:4 decoder/demux in the 74LVC family.
