**Texas Instruments** · Analog Switches, Multiplexers · TSSOP-16

TMUX6211PWR from Texas Instruments, in a TSSOP-16. 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 | SEL1 | input | Logic control input 1 has an internal 4 MΩ pull-down resistor and controls the channel 1 state as shown in Section 8.5. |
| 2 | D1 | bidirectional | Drain pin 1 can be an input or output. |
| 3 | S1 | bidirectional | Source pin 1 can be an input or output. |
| 4 | VSS | power_in | Negative power supply, the most negative power-supply potential; in single-supply applications it can be connected to ground, with a 0.1 µF to 10 µF decoupling capacitor between VSS and GND. |
| 5 | GND | power_in | Ground (0 V) reference. |
| 6 | S4 | bidirectional | Source pin 4 can be an input or output. |
| 7 | D4 | bidirectional | Drain pin 4 can be an input or output. |
| 8 | SEL4 | input | Logic control input 4 has an internal 4 MΩ pull-down resistor and controls the channel 4 state as shown in Section 8.5. |
| 9 | SEL3 | input | Logic control input 3 has an internal 4 MΩ pull-down resistor and controls the channel 3 state as shown in Section 8.5. |
| 10 | D3 | bidirectional | Drain pin 3 can be an input or output. |
| 11 | S3 | bidirectional | Source pin 3 can be an input or output. |
| 12 | N.C. | unconnected | No internal connection; can be shorted to GND or left floating. |
| 13 | VDD | power_in | Positive power supply, the most positive power-supply potential; connect a 0.1 µF to 10 µF decoupling capacitor between VDD and GND. |
| 14 | S2 | bidirectional | Source pin 2 can be an input or output. |
| 15 | D2 | bidirectional | Drain pin 2 can be an input or output. |
| 16 | SEL2 | input | Logic control input 2 has an internal 4 MΩ pull-down resistor and controls the channel 2 state as shown in Section 8.5. |
