SN74LVC2G125DCUR

Texas Instruments · Buffer/Driver/Transceiver · VSSOP-8

SN74LVC2G125DCUR from Texas Instruments, in a VSSOP-8. 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 1OE input Active-low output-enable for buffer 1. When high, 1Y is placed in high-impedance (3-state); when low, buffer 1 is enabled. Tie to VCC through a pullup during power up/down to guarantee Hi-Z.
2 1A input Data input to buffer 1. CMOS input tolerant to 5.5 V independent of VCC.
3 2Y tri_state 3-state buffered output of channel 2. Drives ±24 mA at VCC = 3 V; high-impedance when 2OE is high.
4 GND power_in Device ground reference (0 V).
5 2A input Data input to buffer 2. CMOS input tolerant to 5.5 V independent of VCC.
6 1Y tri_state 3-state buffered output of channel 1. Drives ±24 mA at VCC = 3 V; high-impedance when 1OE is high.
7 2OE input Active-low output-enable for buffer 2. When high, 2Y is placed in high-impedance (3-state); when low, buffer 2 is enabled.
8 VCC power_in Supply voltage, 1.65 V to 5.5 V operating (1.5 V minimum for data retention). Bypass with a 0.1 µF ceramic capacitor close to the pin.

CAD (KiCad official)

  • Symbol: SN74LVC2G125DCUR
  • Footprint: Package_SO:VSSOP-8_2.3x2mm_P0.5mm
  • 3D model: VSSOP-8 (KiCad packages3D, STEP)
  • 3D model files: sn74lvc2g125dcur-etched.step / sn74lvc2g125dcur-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74lvc2g125dcur.step / sn74lvc2g125dcur.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc2g125dcur.step 122 KB You want the bare part, or you mark your own boards.
sn74lvc2g125dcur-etched.step 2.9 MB You want the part with SN74LVC2G125DCUR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 710 faces against 147 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 (15 pp, sha256 9c83f15ae5fa62bc, 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).
