DG4157EDL-T1-GE3 from Vishay, 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	B1	passive	Analog switch throw input/output 1. Connected to A when logic input S = 1. Signal amplitudes up to V+ can be transmitted bidirectionally. Absolute max -0.3 V to 6 V referenced to GND.
2	GND	power_in	Ground reference for the device.
3	B0	passive	Analog switch throw input/output 0. Connected to A when logic input S = 0. Signal amplitudes up to V+ can be transmitted bidirectionally.
4	A	passive	Common analog switch pole (COM). Routes to B0 or B1 depending on the state of the S control input. Powered-off isolation prevents abnormal current flow from A to V+ during power-down.
5	V+	power_in	Positive analog supply, 1.65 V to 5.5 V single-supply operation. Absolute max -0.3 V to 6 V referenced to GND. Typical quiescent current 0.4 nA at V+ = 5.5 V.
6	S	input	Digital select input. S = 0 connects B0 to A; S = 1 connects B1 to A. Guaranteed 1.8 V logic-high threshold (VINH >= 1.8 V, VINL <= 0.6 V) across the full V+ = 2.7-5.5 V range. Input current +/-1 uA max.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`dg4157edl-t1-ge3.step`	99 KB	You want the bare part, or you mark your own boards.
`dg4157edl-t1-ge3-etched.step`	2.2 MB	You want the part with `DG4157EDL-T1-GE3` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 580 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.
