SN74LVC1G125DCKR

Texas Instruments · Buffer/Driver/Transceiver · SC-70-5

SN74LVC1G125DCKR from Texas Instruments, in a SC-70-5. 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 Active-low output enable (OE). When low, the buffer passes A to Y; when high, the Y output is placed in the high-impedance (3-state) condition. Standard CMOS input, accepts up to 5.5 V regardless of VCC. Should be tied to VCC through a pull-up resistor to guarantee Hi-Z during power up/down.
2 A input Buffer data input. Standard CMOS input with high impedance; accepts input voltages up to 5.5 V independent of VCC (supports down-translation to VCC). Do not leave floating during operation.
3 GND power_in Ground (0 V) reference pin for the device.
4 Y tri_state Balanced CMOS 3-state buffer output. Follows the A input when OE is low; high-impedance when OE is high. Drives ±24 mA at VCC = 3.3 V (up to ±32 mA at 4.5 V).
5 VCC power_in Positive supply pin. Recommended operating range 1.65 V to 5.5 V (data retention only down to 1.5 V); absolute max 6.5 V. Typical ICC ≤ 10 µA.

CAD (KiCad official)

  • Symbol: SN74LVC1G125DCKR
  • Footprint: Package_TO_SOT_SMD:SOT-353_SC-70-5
  • 3D model: SC-70-5 (KiCad packages3D, STEP)
  • 3D model files: sn74lvc1g125dckr-etched.step / sn74lvc1g125dckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74lvc1g125dckr.step / sn74lvc1g125dckr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc1g125dckr.step 87 KB You want the bare part, or you mark your own boards.
sn74lvc1g125dckr-etched.step 2.5 MB You want the part with SN74LVC1G125DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 631 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.
