The 8 mA sink current per output drives a standard TTL input with headroom. ## Active, ROHS3, and what that means for a BOM line The SN74LS05DR carries an active lifecycle status from Texas Instruments. No NRND flag, no last-time-buy notice. The part is ROHS3 compliant.","metaTitle":"SN74LS05DR 74LS Hex Inverter, Open Collector, 14-SOIC","metaDescription":"SN74LS05DR from TI: 6-channel inverter with open-collector outputs, 4.75V–5.25V supply, 32ns propagation delay at 5V/15pF. 14-SOIC, 0°C–70°C.","metaKeywords":null},"attributes":{"series":"74LS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"74LS","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Open Collector","Logic Type":"Inverter","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Number of Inputs":"1","Voltage - Supply":"4.75V ~ 5.25V","Number of Circuits":"6","Operating Temperature":"0°C ~ 70°C","Input Logic Level - Low":"0.8V","Supplier Device Package":"14-SOIC","Input Logic Level - High":"2V","Current - Output High, Low":"-, 8mA","Max Propagation Delay @ V, Max CL":"32ns @ 5V, 15pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.95","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.95000","currency":"USD"},{"qty":10,"price":"$0.85400","currency":"USD"},{"qty":25,"price":"$0.81040","currency":"USD"},{"qty":100,"price":"$0.66560","currency":"USD"},{"qty":250,"price":"$0.62216","currency":"USD"},{"qty":500,"price":"$0.54982","currency":"USD"},{"qty":1000,"price":"$0.43407","currency":"USD"},{"qty":2500,"price":"$0.40950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/42a89b0cd2ad29f9fe30bcfdc5d87a13.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SN74LS05DR and SN74LS04?","answer":"Both are hex inverters with the same pinout and supply range. The SN74LS05DR has open-collector outputs; the SN74LS04 has totem-pole (push-pull) outputs. The 74LS05 can sink 8 mA but cannot source current; the 74LS04 can both source and sink. The 74LS05 allows wired-OR connections and level shifting to higher voltages via an external pull-up resistor; the 74LS04 cannot do wired-OR without damaging the outputs."},{"question":"Can SN74LS05DR be used with 5V supply?","answer":"Yes. The SN74LS05DR is designed for a 4.75 V to 5.25 V supply, making it a direct fit for standard 5 V TTL and 5 V CMOS logic systems. The 32 ns propagation delay is specified at 5 V with a 15 pF load."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LS05DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LS05DR when reusing this data.
