SN74LV1T125DBVR

Texas Instruments · Buffer/Driver/Transceiver · SOT-23-5

SN74LV1T125DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OE input Output enable, active low. When OE is low, the buffer drives Y with the level-translated value of A; when OE is high, Y goes to a high-impedance (tri-state) condition. CMOS logic input referenced to VCC with reduced VIH thresholds for level translation.
2 A input Data input A. Accepts CMOS logic input with reduced VIH thresholds (e.g. VIH min ~1.37V at VCC=3.3V) enabling up- or down-level translation to the VCC domain. Tolerant to 5.0V on the input pin regardless of VCC.
3 GND power_in Ground reference (0 V) for the device.
4 Y tri_state Buffered output Y, referenced to VCC. Drives the level-translated logic value of input A when OE is low; enters high-impedance state when OE is high. Output drive: 8 mA at 5V, 7 mA at 3.3V, 3 mA at 1.8V.
5 VCC power_in Positive supply voltage. Recommended operating range 1.6 V to 5.5 V (absolute max 7.0 V). Sets the output logic-level reference for Y.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lv1t125dbvr.step 85 KB You want the bare part, or you mark your own boards.
sn74lv1t125dbvr-etched.step 2.0 MB You want the part with SN74LV1T125DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 528 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (26 pp, sha256 9015da94e1d20a4c, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
