TMUX1219DBVR

Texas Instruments · Analog Switches / Multiplexers · SOT-23-6

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).
