TMUX7219DGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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, which can be an input or output. |
| 2 | S1 | bidirectional | Source pin 1, which can be an input or output. |
| 3 | GND | power_in | Ground (0 V) reference pin. |
| 4 | VDD | power_in | Most positive power-supply pin; a decoupling capacitor of 0.1 µF to 10 µF should be connected between VDD and GND for reliable operation. |
| 5 | EN | input | Active-high logic enable with internal pull-up resistor; when low, all switches are off, and when high, the SEL input selects which switch is on. |
| 6 | SEL | input | Logic control input with internal pull-down resistor that selects the switch connection as described in Section 7.5. |
| 7 | VSS | power_in | Most negative power-supply pin; it can be tied to ground in single-supply use, and a decoupling capacitor of 0.1 µF to 10 µF should be connected between VSS and GND. |
| 8 | S2 | bidirectional | Source pin 2, which can be an input or output. |
