TMUX1237DCKR from Texas Instruments, in a SC-70-6. 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 | S2 | bidirectional | Source pin 2. Can be an input or output of the analog switch. Signal path voltage range: 0 V to VDD, continuous current up to 50 mA. |
| 2 | VDD | power_in | Positive power supply, 1.08 V to 5.5 V. Most positive power-supply potential. Connect a 0.1 µF to 10 µF decoupling capacitor between VDD and GND for reliable operation. |
| 3 | S1 | bidirectional | Source pin 1. Can be an input or output of the analog switch. Signal path voltage range: 0 V to VDD, continuous current up to 50 mA. |
| 4 | D | bidirectional | Drain pin. Common pin of the SPDT switch; can be an input or output. Connects to S1 when SEL = Low, or to S2 when SEL = High. |
| 5 | GND | power_in | Ground (0 V) reference for the device. |
| 6 | SEL | input | Select input: controls state of the SPDT switch. Logic Low connects S1 to D; Logic High connects S2 to D. 1.8 V logic compatible; VIH ≥ 1.32 V (at VDD = 5 V), VIL ≤ 0.87 V. Fail-safe logic tolerates control voltage before VDD is applied. |
