SN74LVC1G3157DC

lingxingic · Analog Switches, Multiplexers · SOT-363

SN74LVC1G3157DC from lingxingic, in a SOT-363. 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 Y1 bidirectional Independent analog I/O 1. Connected to the common Z pin through the analog switch when S = H. Signal range 0 V to VCC; RON ≈ 6.5 Ω @ VCC=3.3 V.
2 GND power_in Ground reference (0 V). Common return for supply and analog signals.
3 Y0 bidirectional Independent analog I/O 0. Connected to the common Z pin through the analog switch when S = L. Signal range 0 V to VCC; RON ≈ 6.5 Ω @ VCC=3.3 V.
4 Z bidirectional Common analog I/O. Routed to either Y0 (S=L) or Y1 (S=H) through the analog switch; supports bidirectional analog or digital signals from 0 V to VCC and up to 32 mA switch current.
5 VCC power_in Positive supply. Recommended operating range 1.65 V to 5.5 V (absolute max 6.5 V). Decouple to GND with a 0.1 µF ceramic capacitor placed close to the pin.
6 S input Digital select input with Schmitt-trigger action. S=L connects Z↔Y0; S=H connects Z↔Y1. TTL-compatible at 3.3 V; input tolerates up to 5.5 V regardless of VCC.

CAD (KiCad official)

  • Symbol: SN74LVC1G3157DC
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: sn74lvc1g3157dc-etched.step / sn74lvc1g3157dc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74lvc1g3157dc.step / sn74lvc1g3157dc.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc1g3157dc.step 99 KB You want the bare part, or you mark your own boards.
sn74lvc1g3157dc-etched.step 2.4 MB You want the part with SN74LVC1G3157DC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 600 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.
