SN74AUP1G125DCKR

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

SN74AUP1G125DCKR 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 Output enable, active low. When OE is low, the buffer drives Y from A; when high, Y is placed in the high-impedance (3-state) state. Must be tied to VCC through a pullup during power-up/down to ensure Hi-Z.
2 A input Data input to the buffer. CMOS-level input with hysteresis; 3.6-V tolerant regardless of VCC.
3 GND power_in Device ground reference. Connect to system ground.
4 Y tri_state Buffered 3-state output. Drives A when OE is low; high-impedance when OE is high. Balanced CMOS push-pull output.
5 VCC power_in Positive supply, 0.8 V to 3.6 V recommended operating range (absolute maximum 4.6 V). Bypass locally with a ceramic capacitor.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74aup1g125dckr.step 87 KB You want the bare part, or you mark your own boards.
sn74aup1g125dckr-etched.step 2.7 MB You want the part with SN74AUP1G125DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 669 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 (56 pp, sha256 36ff026872794b84, 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).
