The output enable (OE) pin, active high, puts the output into high-impedance when low, which is the key difference from the SN74LVC1G125 (active-low OE). Each output can sink or source 32mA, enough to drive a handful of CMOS loads or a short PCB trace. It means this single gate can sit on a 1.8V FPGA I/O bank, a 3.3V microcontroller bus, or a 5V legacy peripheral interface without a separate regulator. The wide tolerance also absorbs supply ripple: a 3.3V rail that droops to 3.0V under load still keeps the buffer in spec. ## Package and footprint — SOT-23-5 layout notes The SN74LVC1G126DBVR ships in a SOT-23-5 package (also designated SC-74A / SOT-753). The 0.95 mm pitch and 2.9 mm body length fit into tight board areas — useful for adding a buffer near a connector or a sensor without a separate logic IC. MSL is 1 (no bake required before reflow if the bag seal is intact), which simplifies assembly logistics. For a production BOM, this removes the single-source risk that comes with an obsolete or phase-out part. The base product number 74LVC1G126 covers the entire family, so if the DBVR (SOT-23-5) reel variant is unavailable, the same die in a different package (e.g., DCKR in SC-70) may be a drop-in alternative after a layout change.","metaTitle":"SN74LVC1G126DBVR Buffer, Non-Inverting, 3-State, 1.65V-5.5V","metaDescription":"Texas Instruments SN74LVC1G126DBVR single buffer with 3-state output, 32mA drive, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Series":"74LVC","Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"-","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"1.65V ~ 5.5V","Number of Elements":"1","Base Product Number":"74LVC1G126","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-5","Current - Output High, Low":"32mA, 32mA","Number of Bits per Element":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbb26954fb99f927b5f5483748cde95a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVC1G126DBVR/alternatives.json"},"ai":{"faq":[{"question":"What package is SN74LVC1G126DBVR in?","answer":"The SN74LVC1G126DBVR is in a SOT-23-5 package, also designated as SC-74A or SOT-753.
