# TMUX1136DQAR

**Texas Instruments** · Analog Switches / Multiplexers · USON-10(1x2.5)

TMUX1136DQAR from Texas Instruments, in a USON-10(1x2.5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SEL1 | input | Selection input pin 1: logic low selects S1B to D1 path, logic high selects S1A to D1 path |
| 2 | S1A | bidirectional | Source pin 1A: bidirectional analog or digital signal input/output from GND to VDD |
| 3 | GND | power_in | Ground (0V) reference potential |
| 4 | S2A | bidirectional | Source pin 2A: bidirectional analog or digital signal input/output from GND to VDD |
| 5 | SEL2 | input | Selection input pin 2: logic low selects S2B to D2 path, logic high selects S2A to D2 path |
| 6 | D2 | bidirectional | Drain pin 2: bidirectional analog or digital signal input/output from GND to VDD |
| 7 | S2B | bidirectional | Source pin 2B: bidirectional analog or digital signal input/output from GND to VDD |
| 8 | VDD | power_in | Positive power supply (1.08V to 5.5V rated range); requires 0.1µF to 10µF decoupling capacitor to GND |
| 9 | S1B | bidirectional | Source pin 1B: bidirectional analog or digital signal input/output from GND to VDD |
| 10 | D1 | bidirectional | Drain pin 1: bidirectional analog or digital signal input/output from GND to VDD |
