It takes a logic input and drives a clean, buffered copy onto the output when the output-enable pin is asserted; when de-asserted, the output goes high-impedance, letting multiple devices share a bus line without contention. ## 8 mA output drive — what it can and cannot sink The output is rated for 8 mA source and 8 mA sink at the rated supply voltage. It will not drive a relay coil directly or fan out to more than a handful of CMOS loads — for heavier loads, plan a transistor or a dedicated line driver after this buffer. ## SOT-23-5 package — rework and footprint It is a hand-solderable size with a standard hot-air station — no thermal pad underneath, so rework is straightforward. The tape-and-reel delivery (TR suffix) is the usual production format for pick-and-place assembly.","metaTitle":"74AHC1G125DBVRG4 Buffer, Non-Inverting, 3-State, SOT-23-5","metaDescription":"TI 74AHC1G125DBVRG4 single buffer with 3-state output, 2V-5.5V supply, 8mA drive, industrial temp range.","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)","Input Type":"-","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","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":"SOT-23-5","Current - Output High, Low":"8mA, 8mA","Number of Bits per Element":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b51c1efe42b8af8a411d01ad16a968ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/74AHC1G125DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 74AHC1G125DBVRG4 in this component family?","answer":"Within the 74AHC family, the 74AHC1G125DCKR (SOT-353 package) is functionally identical but uses a different footprint. For a drop-in SOT-23-5 replacement, look at the 74LVC1G125DBVR from the LVC family — same pinout, same package, but operates down to 1.65V. Verify the supply voltage and output drive against your design before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74AHC1G125DBVRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74AHC1G125DBVRG4 when reusing this data.
