# TMUX154ERSWR

**Texas Instruments** · Analog Switches, Multiplexers · UQFN-10(1.4x1.8)

TMUX154ERSWR from Texas Instruments, in a UQFN-10(1.4x1.8). 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 | A0 | bidirectional | Differential signal path port 0 for channel A |
| 2 | A1 | bidirectional | Differential signal path port 1 for channel A |
| 3 | A | bidirectional | Common differential signal path for channel A; routes to A0 or A1 based on SEL when EN = 0 |
| 4 | GND | power_in | Ground |
| 5 | B | bidirectional | Common differential signal path for channel B; routes to B0 or B1 based on SEL when EN = 0 |
| 6 | B1 | bidirectional | Differential signal path port 1 for channel B |
| 7 | B0 | bidirectional | Differential signal path port 0 for channel B |
| 8 | EN | input | Enable control input; EN = 0 enables switch, EN = 1 disables switch placing all signal paths in high impedance state |
| 9 | VCC | power_in | Positive supply voltage; 3 V to 4.3 V operating range |
| 10 | SEL | input | Select control input; SEL = 0 routes A,B to A0,B0; SEL = 1 routes A,B to A1,B1 when EN = 0 |
