It selects one of two 4-bit data sources under control of a common select input, with a single supply range of 4.5V to 5.5V. ## Supply rail and output drive The 4.5V to 5.5V single-supply range is a direct match for 5V TTL and HCMOS systems. The 6mA output high and low current is typical for the 74HCT family and drives standard CMOS or TTL loads without an external buffer. If your load requires more than 6 mA per channel, plan for a line driver or a higher-drive logic family.","metaTitle":"SN74HCT157N 74HCT Quad 2:1 Multiplexer, 16-DIP, 4.5V–5.5V","metaDescription":"Texas Instruments SN74HCT157N is a 4 x 2:1 multiplexer in 16-DIP, 4.5V–5.5V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Multiplexer","Series":"74HCT","Circuit":"4 x 2:1","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":"-40°C ~ 85°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"16-PDIP","Current - Output High, Low":"6mA, 6mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.85","priceTiers":[{"qty":1,"price":"$0.85000","currency":"USD"},{"qty":10,"price":"$0.74500","currency":"USD"},{"qty":25,"price":"$0.70000","currency":"USD"},{"qty":100,"price":"$0.57120","currency":"USD"},{"qty":250,"price":"$0.53060","currency":"USD"},{"qty":500,"price":"$0.45156","currency":"USD"},{"qty":1000,"price":"$0.36125","currency":"USD"},{"qty":2500,"price":"$0.32738","currency":"USD"},{"qty":5000,"price":"$0.31950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/90172125e79a3fd5c4cc33d1f8cb22c2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74HCT157N/alternatives.json"},"ai":{"faq":[{"question":"What is the SN74HCT157N?","answer":"The SN74HCT157N is a Texas Instruments 74HCT-series quad 2:1 multiplexer in a 16-pin DIP package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74HCT157N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74HCT157N when reusing this data.
