The low-level threshold is 0.5 V, the high-level threshold is 1.9 V. ## Where it fits — and where it doesn't This part is rated 0°C to 70°C. The 14-DIP package is through-hole. Output drive is 400 µA sourcing, 8 mA sinking. ## Active, no obsolescence pressure ROHS3 compliant. For a legacy 5 V TTL design still in the field or a new build that needs a through-hole Schmitt inverter, this part is available through independent distribution.","metaTitle":"SN74LS14N Texas Instruments 74LS Hex Schmitt-Trigger","metaDescription":"SN74LS14N — 6-channel Schmitt-trigger inverter, 4.75–5.25 V supply, 22 ns propagation delay, 14-DIP through-hole.","metaKeywords":null},"attributes":{"series":"74LS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"74LS","Package":"Tube","Features":"Schmitt Trigger","Logic Type":"Inverter","Mounting Type":"Through Hole","Package / Case":"14-DIP (0.300\\\", 7.62mm)","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":"0.5V","Supplier Device Package":"14-PDIP","Input Logic Level - High":"1.9V","Current - Output High, Low":"400µA, 8mA","Max Propagation Delay @ V, Max CL":"22ns @ 5V, 15pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.85","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.85000","currency":"USD"},{"qty":10,"price":"$0.74900","currency":"USD"},{"qty":25,"price":"$0.70320","currency":"USD"},{"qty":100,"price":"$0.57390","currency":"USD"},{"qty":250,"price":"$0.53308","currency":"USD"},{"qty":500,"price":"$0.45368","currency":"USD"},{"qty":1000,"price":"$0.36294","currency":"USD"},{"qty":2500,"price":"$0.32892","currency":"USD"},{"qty":5000,"price":"$0.32100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ce6eaf85598b522c720e7cc12f7c7f90.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74LS14N compatible with 5V TTL logic?","answer":"Yes. The supply range is 4.75 V to 5.25 V, and the input thresholds (0.5 V low, 1.9 V high) are directly compatible with standard 5 V TTL outputs. The outputs drive standard LS-TTL loads without extra buffering."},{"question":"What is the difference between SN74LS14N and SN74LS04?","answer":"Both are hex inverters in the same 14-DIP package and pinout, but the SN74LS14N has Schmitt-trigger inputs with hysteresis (0.5 V low threshold, 1.9 V high threshold), while the SN74LS04 uses standard TTL input levels. Use the '14 when you need noise immunity on slow or noisy signal lines — for clean digital rails, the '04 is sufficient."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LS14N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LS14N when reusing this data.
