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. |

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.
