TCA9517DR

Texas Instruments · Translators / Level Shifters · SOIC-8

TCA9517DR from Texas Instruments, in a SOIC-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 VCCA power_in A-side supply voltage (0.9 V to 5.5 V). Provides the 0.3 x VCCA reference to the A-side input comparators and powers the power-good-detect circuit.
2 SCLA bidirectional Serial clock bus, A-side. Open-drain I/O; connect to VCCA through a pull-up resistor. If unused, connect directly to ground.
3 SDAA bidirectional Serial data bus, A-side. Open-drain I/O; connect to VCCA through a pull-up resistor. If unused, connect directly to ground.
4 GND power_in Device ground reference.
5 EN input Active-high repeater enable input. VIH = 0.7 x VCCB min, VIL = 0.3 x VCCB max. Drive high to enable bidirectional buffering between A and B sides.
6 SDAB bidirectional Serial data bus, B-side. Open-drain I/O; connect to VCCB through a pull-up resistor. If unused, connect directly to ground.
7 SCLB bidirectional Serial clock bus, B-side. Open-drain I/O; connect to VCCB through a pull-up resistor. If unused, connect directly to ground.
8 VCCB power_in B-side and device supply voltage (2.7 V to 5.5 V). Powers the TCA9517 logic and all internal I/O drivers.

CAD (KiCad official)

  • Symbol: TCA9517DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tca9517dr-etched.step / tca9517dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tca9517dr.step / tca9517dr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (28 pp, sha256 fde93fd601168d6f, 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).
