It operates from 2V to 6V supply and -40°C to 85°C temperature range. ## Ratings that decide the fit The 4 x 2:1 circuit routes four bits at once. Supply range is 2V to 6V. Output drive is 7.8 mA per pin. Package is 16-SOIC. ## Lifecycle and sourcing reality TI keeps the 74HC family running for industrial and legacy-support customers. For a BOM line, this means no supply risk from obsolescence; you can qualify it for new designs without worrying about a sudden discontinuation.","metaTitle":"SN74HC158DT 74HC Multiplexer, 4 x 2:1, 16-SOIC, Active","metaDescription":"TI SN74HC158DT 74HC CMOS multiplexer, 4 x 2:1 circuit, 2V–6V supply, -40°C to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":"74HC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Multiplexer","Series":"74HC","Circuit":"4 x 2:1","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 6V","Independent Circuits":"1","Operating Temperature":"-40°C ~ 85°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"16-SOIC","Current - Output High, Low":"7.8mA, 7.8mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.16","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.16000","currency":"USD"},{"qty":10,"price":"$1.03500","currency":"USD"},{"qty":25,"price":"$0.98240","currency":"USD"},{"qty":100,"price":"$0.80700","currency":"USD"},{"qty":250,"price":"$0.75436","currency":"USD"},{"qty":500,"price":"$0.66664","currency":"USD"},{"qty":1250,"price":"$0.52629","currency":"USD"},{"qty":2500,"price":"$0.49650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/65a91b1d1f191eaaae8fae97fb91bd8c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the function of SN74HC158DT?","answer":"It is a 4-channel, 2-input to 1-output CMOS multiplexer.
