TMUX1219DBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SEL | input | Select input: controls the switch state per the truth table. Logic Low routes S1 to D; Logic High routes S2 to D. 1.8 V logic compatible thresholds; fail-safe logic allows voltage before VDD is applied. Absolute max input voltage -0.5 V to 6 V. |
| 2 | VDD | power_in | Positive power supply. Most positive supply potential; recommended operating range 1.08 V to 5.5 V (absolute max 6 V). Connect a 0.1 µF to 10 µF decoupling capacitor between VDD and GND for reliable operation. |
| 3 | GND | power_in | Ground (0 V) reference for the device and switch signals. |
| 4 | S1 | bidirectional | Source pin 1 of the SPDT switch. Bidirectional analog/digital signal path to the drain (D) when SEL = Low. Signal range GND to VDD; on-resistance ~3 Ω; continuous current ±30 mA (abs max). |
| 5 | D | bidirectional | Common drain pin of the SPDT switch. Bidirectional analog/digital connection to S1 or S2 depending on SEL. Signal range GND to VDD; on-resistance ~3 Ω; continuous current ±30 mA (abs max). |
| 6 | S2 | bidirectional | Source pin 2 of the SPDT switch. Bidirectional analog/digital signal path to the drain (D) when SEL = High. Signal range GND to VDD; on-resistance ~3 Ω; continuous current ±30 mA (abs max). |
