# TMUX6119DCNR

**Texas Instruments** · Analog Switches, Multiplexers · SOT-23-8

TMUX6119DCNR from Texas Instruments, in a SOT-23-8. 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 | EN | input | High-level active digital input; when low, both switches are off; when high, SEL logic input determines which switch opens. |
| 2 | VDD | power_in | Positive power supply pin at highest potential; connect 0.1µF to 10µF decoupling capacitor between VDD and GND for reliable operation. |
| 3 | GND | power_in | Ground (0V) reference. |
| 4 | VSS | power_in | Negative power supply pin at highest potential of negative supply; can be tied to ground in single-supply applications; connect 0.1µF to 10µF decoupling capacitor between VSS and GND. |
| 5 | SB | bidirectional | Source pin B; can function as input or output. |
| 6 | D | bidirectional | Drain pin; can function as input or output. |
| 7 | SA | bidirectional | Source pin A; can function as input or output. |
| 8 | SEL | input | Logic control input. |
