GS4157B-CR

Gainsil · Analog Switches, Multiplexers · SC-70-6

GS4157B-CR from Gainsil, in a SC-70-6. 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 NO passive Normally-Open analog switch throw. Connected to COM when IN is logic high. Analog signal range Vss to VDD; on-resistance 0.8Ω typ at Vs=4.5V.
2 VSS power_in Negative supply / ground reference. Typically tied to GND for single-supply operation.
3 NC unconnected No connect. Leave floating or tie as recommended by application; not internally bonded.
4 COM passive Common analog pole of the SPDT switch. Routes to NO when IN=high (break-before-make). Analog signal range Vss to VDD.
5 VDD power_in Positive supply input, +1.8V to +5.5V single-supply operation. Decouple with 0.1μF to VSS. Absolute max VDD-VSS = +7.5V.
6 IN input Digital control input selecting the switch state. TTL/CMOS compatible; VINH ≥ 1.5V (Vs=5V), VINL ≤ 0.55V (Vs=5V). Tolerates drive up to 5.5V independent of VDD.

Two STEP files. Same geometry, different body top:

File Size Use it when
gs4157b-cr.step 99 KB You want the bare part, or you mark your own boards.
gs4157b-cr-etched.step 2.0 MB You want the part with GS4157B-CR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 487 faces against 117 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: Gainsil datasheet (9 pp, sha256 211dfbbd95b0d179, 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).
