The 5-DSBGA package (1.4x0.9 mm) is a wafer-level chip-scale package — no leads, no exposed pad — designed for space-constrained assemblies where a standard SOT-23 or SC-70 footprint won't fit. If the board can tolerate a package change, the more common SN74LVC1G126DCK (SOT-23-5) or SN74LVC1G126DBV (SOT-23-5) are still active and widely stocked, but they are not pin-compatible with the DSBGA land pattern. The wide supply range lets this buffer bridge a 1.8V MCU to a 3.3V or 5V peripheral without a separate level shifter. The 32mA symmetric drive at both logic highs and lows is enough to switch a small signal relay or a MOSFET gate through a series resistor. The 3-state output allows multiple buffers to share a bus line — useful in multiplexed address or data lines where the output goes high-impedance when not selected. ## 5-DSBGA — assembly and rework considerations It requires a PCB land pattern with 0.5 mm pitch and a solder-mask-defined pad. Rework is difficult — the package is fragile and typically requires hot-air rework with a preheat plate. For prototyping or low-volume production, the SOT-23-5 variant (SN74LVC1G126DCK) is easier to hand-solder and probe, though the footprint is different.","metaTitle":"SN74LVC1G126YEAR Buffer, 1.65V-5.5V, 32mA, Obsolete","metaDescription":"Texas Instruments SN74LVC1G126YEAR single non-inverting buffer with 3-state output, 1.65V-5.5V supply, 32mA drive, -40°C to 85°C, 5-DSBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"5-XFBGA, DSBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"1.65V ~ 5.5V","Number of Elements":"1","Base Product Number":"74LVC1G126","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"5-DSBGA (1.4x0.9)","Current - Output High, Low":"32mA, 32mA","Number of Bits per Element":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbb26954fb99f927b5f5483748cde95a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVC1G126YEAR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for SN74LVC1G126YEAR?","answer":"Texas Instruments has not published an official replacement for the SN74LVC1G126YEAR.
