TMUX7219RQXR from Texas Instruments, in a WSON-8(2x3). 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). |
