The 1.65V to 3.6V supply range lets it bridge 1.8V and 3.3V logic domains without a level shifter — useful in mixed-voltage designs where an FPGA or low-voltage MCU needs to decode addresses for a 3.3V peripheral bank. ## Supply voltage and output drive — the BOM-fit checks The 1.65V minimum supply covers 1.8V logic rails (LPDDR I/O, many Cortex-M parts), while the 3.6V max handles 3.3V and 2.5V families. That single-supply operation avoids a second regulator if the rest of the board already runs at one of these voltages. The 24mA output sink and source capability at 3.3V gives enough fan-out to drive four or five standard CMOS loads directly; if you're driving a long trace or a high-capacitance bus, budget for signal-integrity checks at the far end. ## Industrial temperature range — where it runs It suits outdoor telecom cabinets, factory-floor PLC I/O modules, and HVAC controllers where the ambient inside the enclosure can push past 70°C. No AEC-Q100 automotive qualification on this suffix, so it stays out of under-hood or chassis-domain designs unless you qualify it yourself.","metaTitle":"SN74LVC139APWT Decoder/Demultiplexer, 1.65V-3.6V, 16-TSSOP","metaDescription":"Texas Instruments SN74LVC139APWT dual 2:4 decoder/demultiplexer in 16-TSSOP. 1.65V to 3.6V supply, 24mA output drive, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"74LVC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Decoder/Demultiplexer","Series":"74LVC","Circuit":"1 x 2:4","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.65V ~ 3.6V","Independent Circuits":"2","Operating Temperature":"-40°C ~ 85°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"16-TSSOP","Current - Output High, Low":"24mA, 24mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.31","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.31000","currency":"USD"},{"qty":10,"price":"$1.16900","currency":"USD"},{"qty":25,"price":"$1.11000","currency":"USD"},{"qty":100,"price":"$0.91180","currency":"USD"},{"qty":250,"price":"$0.85236","currency":"USD"},{"qty":500,"price":"$0.75324","currency":"USD"},{"qty":1250,"price":"$0.59466","currency":"USD"},{"qty":2500,"price":"$0.56100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/32839f78b80e5dc2c1d477c357806656.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does SN74LVC139APWT come in?","answer":"It comes in a 16-TSSOP package (0.173\" body width, 4.40mm width) for surface-mount assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LVC139APWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LVC139APWT when reusing this data.
