RS2166XC5

Jiangsu RUNIC Tech · Analog Switches, Multiplexers · SOT-353

RS2166XC5 from Jiangsu RUNIC Tech, in a SOT-353. 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 S bidirectional Source: bidirectional analog/digital signal terminal of the SPST switch. Signal range 0 to VCC (rail-to-rail); interchangeable with D - either may serve as input or output.
2 D bidirectional Drain: bidirectional analog/digital signal terminal of the SPST switch. Signal range 0 to VCC (rail-to-rail); interchangeable with S.
3 GND power_in Ground reference. Continuous current through VCC or GND limited to ±100mA (abs max).
4 SEL input Digital switch enable input. Logic High turns the switch ON, Logic Low turns it OFF. TTL/CMOS compatible: VIH ≥ 1.5V (5V) / 1.3V (3.3V); VIL ≤ 0.6V (5V) / 0.5V (3.3V). Input leakage ≤ 1µA. Must not be left floating.
5 VCC power_in Positive supply. Recommended operating range 1.8V to 5.5V; absolute max 6.0V. Quiescent supply current ICC ≤ 1µA at 5.5V.

Ordering variants

Same part, different packaging or reel option.

  • RS2166XC5
  • RS2166XC5XF5

CAD (KiCad official)

  • Symbol: RS2166XC5
  • Footprint: Package_TO_SOT_SMD:SOT-353_SC-70-5
  • 3D model: SOT-353 (KiCad packages3D, STEP)
  • 3D model files: rs2166xc5-etched.step / rs2166xc5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs2166xc5.step / rs2166xc5.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rs2166xc5.step 87 KB You want the bare part, or you mark your own boards.
rs2166xc5-etched.step 2.1 MB You want the part with RS2166XC5 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 492 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: Jiangsu RUNIC Tech datasheet (12 pp, sha256 0f3e58f75912b0d4, retrieved 2026-08-17, tier: lcsc)
  • 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).
