TMUX1108RSVR from Texas Instruments, in a UQFN-16(1.8x2.6). 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 | VSS | power_in | Negative power supply (-2.75V to 0V); most negative potential; requires 0.1µF to 10µF decoupling capacitor to GND. |
| 2 | S1 | bidirectional | Source pin 1; bidirectional signal path (input/output); signal voltage VSS to VDD; continuous current ±150mA at 25°C. |
| 3 | S2 | bidirectional | Source pin 2; bidirectional signal path (input/output); signal voltage VSS to VDD; continuous current ±150mA at 25°C. |
| 4 | S3 | bidirectional | Source pin 3; bidirectional signal path (input/output); signal voltage VSS to VDD; continuous current ±150mA at 25°C. |
| 5 | S4 | bidirectional | Source pin 4; bidirectional signal path (input/output); signal voltage VSS to VDD; continuous current ±150mA at 25°C. |
| 6 | D | bidirectional | Drain pin; bidirectional signal path (input/output); signal voltage VSS to VDD; continuous current ±150mA at 25°C. |
| 7 | S8 | bidirectional | Source pin 8; bidirectional signal path (input/output); signal voltage VSS to VDD; continuous current ±150mA at 25°C. |
| 8 | S7 | bidirectional | Source pin 7; bidirectional signal path (input/output); signal voltage VSS to VDD; continuous current ±150mA at 25°C. |
| 9 | S6 | bidirectional | Source pin 6; bidirectional signal path (input/output); signal voltage VSS to VDD; continuous current ±150mA at 25°C. |
| 10 | S5 | bidirectional | Source pin 5; bidirectional signal path (input/output); signal voltage VSS to VDD; continuous current ±150mA at 25°C. |
| 11 | VDD | power_in | Positive power supply (1.08V to 5.5V); most positive potential; requires 0.1µF to 10µF decoupling capacitor to GND. |
| 12 | GND | power_in | Ground (0V) reference. |
| 13 | A2 | input | Address line 2; logic input (0V to 5.5V) compatible with 1.8V logic levels. |
| 14 | A1 | input | Address line 1; logic input (0V to 5.5V) compatible with 1.8V logic levels. |
| 15 | A0 | input | Address line 0; logic input (0V to 5.5V) compatible with 1.8V logic levels. |
| 16 | EN | input | Enable input (0V to 5.5V); when low all switches are off; when high A[2:0] selects active switch. |

Package_DFN_QFN:UQFN-16_1.8x2.6mm_P0.4mm - 3D model: UQFN-16(1.8x2.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal UFQFPN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
