The 3-state output allows the device to disconnect from a shared bus, useful in multiplexed I²C, SPI chip-select, or general-purpose enable/disable gating. ## Supply range and level-shifting capability Running the buffer at 3.3 V while the input comes from a 1.8 V peripheral works because the 74LVC family's input thresholds are CMOS-compatible across the full range — no external level shifter needed. This saves board area and BOM cost in mixed-voltage designs like sensor interfaces, FPGA configuration, or legacy 5 V tolerant bus buffering. The wide temperature range also covers cold-crank and hot-soak conditions in engine-adjacent electronics, though it lacks formal AEC-Q100 qualification in the record — verify against your OEM's specific automotive-grade requirement if that is your target. ## Output drive and bus fan-out Symmetric 32 mA source and sink capability at both high and low output states is unusual for a single-gate logic device. It drives multiple CMOS loads or a short PCB trace without needing a dedicated buffer line driver. In a 3.3 V system, 32 mA translates to roughly a 100 Ω equivalent output impedance — enough to drive a 50 Ω controlled-impedance trace for a few inches, but not a long backplane cable. Supplied in a 5-pin SOT-23-5 package (also designated SC-74A), the footprint is industry-standard for single-gate logic. The same pad layout is shared across the 74LVC1G family and many competitors' single-gate buffers, simplifying last-minute alternate sourcing on the PCB. Listed as Active in the lifecycle record — no end-of-life notification, no last-time-buy window. For BOM qualification into new designs, there is no looming obsolescence risk.","metaTitle":"Texas Instruments 74LVC1G126DBVRE4 Buffer, Non-Inverting","metaDescription":"74LVC1G126DBVRE4 single-gate buffer from TI, 74LVC series, 1.65V–5.5V supply, 32mA output, -40°C to 125°C.

The 'DBVRE4' suffix on this part indicates a specific reel and packaging option (Tape & Reel). For a BOM line, SN74LVC1G126DBVR is the direct functional and footprint alternate — verify the reel quantity matches your production needs."},{"question":"Can 74LVC1G126DBVRE4 be used as a level shifter?","answer":"Yes. When the device is powered from the higher-voltage rail (e.g., 3.3 V), a 1.8 V logic input is still recognized as a valid high because the 74LVC family's input thresholds are referenced to VCC. The output then swings to the supply rail, effectively performing unidirectional level shifting from low to high voltage. For bidirectional level shifting, a dedicated translator like the TXB0104 is more appropriate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74LVC1G126DBVRE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74LVC1G126DBVRE4 when reusing this data.
