Output drive capability is 5.2mA for both high and low states, sufficient to fan out to up to ten standard LSTTL loads or drive the inputs of downstream CMOS logic without buffering. ## 16-SOIC package — surface-mount integration The surface-mount profile suits automated pick-and-place assembly and reflow soldering. ROHS3 compliant, the part carries no RoHS exemption conflicts for EU-market shipments.","metaTitle":"SN74HC259DT Texas Instruments 74HC Addressable Latch, 1:8","metaDescription":"SN74HC259DT Texas Instruments 74HC D-Type Addressable Latch, 1:8 demultiplexer, 2V-6V supply, -40°C to 85°C, 13ns propagation delay, 16-SOIC.","metaKeywords":null},"attributes":{"series":"74HC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74HC","Circuit":"1:8","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"D-Type, Addressable","Output Type":"Standard","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","Supplier Device Package":"16-SOIC","Delay Time - Propagation":"13ns","Current - Output High, Low":"5.2mA, 5.2mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.26","priceTiers":[{"qty":1,"price":"$1.26000","currency":"USD"},{"qty":10,"price":"$1.12600","currency":"USD"},{"qty":25,"price":"$1.06840","currency":"USD"},{"qty":100,"price":"$0.87770","currency":"USD"},{"qty":250,"price":"$0.82044","currency":"USD"},{"qty":500,"price":"$0.72504","currency":"USD"},{"qty":1250,"price":"$0.57240","currency":"USD"},{"qty":2500,"price":"$0.54000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e83ef83835322314921e34cf38c10e80.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74HC259DT/alternatives.json"},"ai":{"faq":[{"question":"What is the function of the SN74HC259DT?","answer":"It is a D-Type Addressable Latch configured as a 1:8 demultiplexer.
