The 32 mA sink and source capability is enough to directly drive a low-current LED or fan out to several CMOS loads, though for higher fan-out you would buffer through a second gate. The 1.65 V minimum supply means this part works with 1.8 V logic families (JEDEC standard) and even the low end of a 1.8 V rail with some margin. The 5.5 V maximum covers 5 V nominal rails plus a reasonable tolerance, so you do not need a separate 5 V-tolerant buffer for mixed-voltage boards. ## Output drive — 32 mA sink and source For a typical 3.3 V system, 32 mA can drive a 100 Ω series-terminated trace or a standard LED with a current-limiting resistor. If you need to drive a heavier load like a relay coil or a long cable, plan on a discrete transistor or a dedicated driver; this buffer is sized for signal-level fan-out, not power switching. ## Package and footprint — SOT-23-5 Housed in an SC-74A / SOT-23-5 package, this part uses a standard five-pin footprint shared by many single-gate logic devices. The small body saves board area — useful when you need just one buffer in a corner of a dense PCB. No last-time-buy risk or obsolescence concern for new designs.","metaTitle":"SN74LVC1G126DBVT Buffer, Non-Inverting, 3-State, 1.65V-5.5V","metaDescription":"Texas Instruments SN74LVC1G126DBVT single-gate buffer with 3-state output, 32mA drive, -40°C to 125°C range.

The DBVT variant uses the SOT-23-5 footprint, which is mechanically different but electrically identical. For a direct drop-in, any SOT-23-5 single-gate buffer with the same pinout (1 = OE, 2 = input, 3 = GND, 4 = output, 5 = VCC) from the 74LVC or 74AUC series will fit, but verify the supply range and drive current against your design."},{"question":"Is SN74LVC1G126DBVT compatible with 3.3 V logic?","answer":"Yes. The supply range of 1.65 V to 5.5 V includes 3.3 V, and the 32 mA output drive at 3.3 V is sufficient for standard CMOS and TTL inputs. The 3-state output allows bus sharing when the output enable pin is pulled low."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LVC1G126DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LVC1G126DBVT when reusing this data.
