TMUX1248DCKR

Texas Instruments · Analog Switches / Multiplexers · SC-70-6

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.
