SN74LVC1G3157T236

XBLW · Analog Switches, Multiplexers · SOT-23-6

SN74LVC1G3157T236 from XBLW, in a SOT-23-6. 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 Y1 bidirectional Independent analog input/output channel 1. Connected to common pin Z through the internal analog switch when select input S is HIGH. Switch current capability 32 mA; signal range 0 V to Vcc.
2 GND power_in Ground reference (0 V). All voltages referenced to this pin.
3 Y0 bidirectional Independent analog input/output channel 0. Connected to common pin Z through the internal analog switch when select input S is LOW. Switch current capability 32 mA; signal range 0 V to Vcc.
4 Z bidirectional Common analog input/output pin. Routed to either Y0 (when S=L) or Y1 (when S=H) through the internal bidirectional analog switch. Signal range 0 V to Vcc.
5 VCC power_in Positive supply voltage input. Recommended operating range 1.65 V to 5.5 V; absolute maximum 6.5 V. Bypass with a local decoupling capacitor to GND.
6 S input Digital select input with Schmitt-trigger action. S=LOW routes Y0<->Z; S=HIGH routes Y1<->Z. Control input tolerates voltages up to 5.5 V independent of Vcc; TTL/CMOS compatible.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc1g3157t236.step 97 KB You want the bare part, or you mark your own boards.
sn74lvc1g3157t236-etched.step 2.6 MB You want the part with SN74LVC1G3157T236 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 652 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: XBLW datasheet (21 pp, sha256 c63d8ff05ef91d31, 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).
