It takes one input and drives one output with an active-low output enable (OE). When OE is high, the output goes high-impedance, letting multiple buffers share a bus without contention. Output drive is rated at 8 mA source and sink, enough for standard CMOS logic fan-out but not for driving a relay coil or LED directly. No special cooling needed at the 8 mA output level, but the SC-70-5 package's thermal resistance means derating the output current above 85°C if you push continuous drive.","metaTitle":"74AHC1G125DCKRG4 Buffer, Non-Inverting, 3-State, 2V-5.5V","metaDescription":"74AHC1G125DCKRG4 from Texas Instruments is a single-bit buffer with 3-state output, 2V to 5.5V supply, -40°C to 125°C range, SC-70-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Series":"74AHC","Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"-","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 5.5V","Number of Elements":"1","Base Product Number":"74AHC1G125","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SC-70-5","Current - Output High, Low":"8mA, 8mA","Number of Bits per Element":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b51c1efe42b8af8a411d01ad16a968ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/74AHC1G125DCKRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between 74AHC1G125 and 74LVC1G125?","answer":"The 74LVC1G125 operates down to 1.65 V and typically offers 5 V tolerant inputs, while the 74AHC1G125 starts at 2 V and lacks 5 V tolerant I/O. The LVC variant also has lower dynamic power at higher frequencies. For 3.3 V or 5 V-only rails without mixed-voltage interfaces, the AHC part is functionally equivalent and often priced lower."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74AHC1G125DCKRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74AHC1G125DCKRG4 when reusing this data.
