SN74LVC1G17DCKR

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

SN74LVC1G17DCKR 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 NC unconnected No internal connection. Leave floating or tie to a static level; not electrically bonded inside the SC70-5 (DCK) package.
2 A input Schmitt-trigger logic input. Positive-going threshold VT+ = 1.48-1.92 V at VCC = 3 V and negative-going threshold VT− = 0.89-1.2 V (hysteresis ~0.51-0.83 V). Input voltage range 0 to 5.5 V (5-V tolerant regardless of VCC). Do not leave floating in operation.
3 GND power_in Device ground / 0 V reference. Connect to system ground with a low-inductance path; decouple VCC to GND with a 0.1 µF ceramic close to the pin.
4 Y output CMOS push-pull buffer output, Y = A. Drive strength ±24 mA at VCC = 3 V (IOH/IOL, VOH ≥ 2.4 V / VOL ≤ 0.4 V). Propagation delay tpd ≈ 1.5 ns typical (max 4.6 ns) at 3.3 V with CL = 15 pF.
5 VCC power_in Positive supply, 1.65 V to 5.5 V operating (1.5 V data retention only). Absolute max 6.5 V. Decouple to GND with 0.1 µF at the pin; ICC ≤ 10 µA static.

CAD (KiCad official)

  • Symbol: SN74LVC1G17DCKR
  • Footprint: Package_TO_SOT_SMD:SOT-353_SC-70-5
  • 3D model: SC-70-5 (KiCad packages3D, STEP)
  • 3D model files: sn74lvc1g17dckr-etched.step / sn74lvc1g17dckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74lvc1g17dckr.step / sn74lvc1g17dckr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc1g17dckr.step 87 KB You want the bare part, or you mark your own boards.
sn74lvc1g17dckr-etched.step 2.2 MB You want the part with SN74LVC1G17DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 556 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 (53 pp, sha256 2570a9354a9b24e7, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
