Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | D | bidirectional | Drain pin that can be an input or output; analog and digital signals on D range from VSS to VDD, with absolute limits of VSS-0.5 V to VDD+0.5 V. |+| 2 | S1 | bidirectional | Source pin 1 that can be an input or output; signals range from VSS to VDD, and the path S1 to D is selected through SEL when EN is high. |+| 3 | GND | power_in | Ground (0 V) reference for the device. |+| 4 | VDD | power_in | Most positive power-supply pin; connect a decoupling capacitor of 0.1 µF to 10 µF between VDD and GND for reliable operation. |+| 5 | EN | input | Active-high logic enable with an internal pull-up resistor; when low, all switches are off, and when high, SEL determines which switch is on. |+| 6 | SEL | input | Logic control input with an internal pull-down resistor that selects the switch connection as described in Section 8.5. |+| 7 | VSS | power_in | Most negative power-supply pin; may be tied to ground in single-supply use, with a 0.1 µF to 10 µF decoupling capacitor between VSS and GND for reliable operation. |+| 8 | S2 | bidirectional | Source pin 2 that can be an input or output; signals range from VSS to VDD, and the path S2 to D is selected through SEL when EN is high. |+| 9 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WSON-8(2x3) |+| Category | Interface |+| Pins | 9 |++## CAD (KiCad official)++- Symbol: `TMUX7219RQXR`+- Footprint: `Package_SON:SON-8-1EP_3x2mm_P0.5mm_EP1.4x1.6mm`+- 3D model: WSON-8(2x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN height).
