SN74LVC1G3157T363

XBLW · Analog Switches, Multiplexers · SOT-363

SN74LVC1G3157T363 from XBLW, 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 input/output channel 1. Connected to common terminal Z when select input S = HIGH. Bidirectional analog switch terminal; supports signals from GND to Vcc (up to 5.5 V) with switch current capability of 32 mA.
2 GND power_in Ground reference (0 V). All voltages in the datasheet are referenced to this pin.
3 Y0 bidirectional Independent analog input/output channel 0. Connected to common terminal Z when select input S = LOW. Bidirectional analog switch terminal; supports signals from GND to Vcc.
4 Z bidirectional Common analog output/input (pole of the SPDT). Routed to Y0 when S=LOW or to Y1 when S=HIGH via break-before-make switching.
5 VCC power_in Positive supply voltage input. Operating range 1.65 V to 5.5 V; absolute max +6.5 V. Typical ICC ≤ 4 µA.
6 S input Digital select input with Schmitt-trigger action. S=LOW selects Y0↔Z; S=HIGH selects Y1↔Z. Accepts control voltages up to 5.5 V independent of Vcc, TTL-compatible at Vcc=3.3 V.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc1g3157t363.step 99 KB You want the bare part, or you mark your own boards.
sn74lvc1g3157t363-etched.step 3.0 MB You want the part with SN74LVC1G3157T363 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 724 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.
