TMUX1248DCKR 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 of the SPDT analog switch. Can be an input or output; signal path handles bidirectional analog/digital signals from GND to VDD (1.08 V to 5.5 V range). |
| 2 | GND | power_in | Ground (0 V) reference for the device. |
| 3 | S1 | bidirectional | Source pin 1 of the SPDT analog switch. Can be an input or output; signal path handles bidirectional analog/digital signals from GND to VDD. |
| 4 | D | bidirectional | Drain (common) pin of the SPDT analog switch. Connects to either S1 or S2 depending on the SEL state; can be an input or output. |
| 5 | VDD | power_in | Positive power supply, most positive rail of the device. Operating range 1.08 V to 5.5 V; connect a 0.1 µF to 10 µF decoupling capacitor between VDD and GND for reliable operation. |
| 6 | SEL | input | Digital select input controlling which source (S1 or S2) is connected to D per the truth table. 1.8 V logic compatible (VIH ≥ 1.42 V at VDD = 5 V) with fail-safe logic and 5.5 V overvoltage tolerance independent of VDD. |
