**Texas Instruments** · Analog Switches, Multiplexers · MSOP-10

TMUX154EDGSR from Texas Instruments, in a MSOP-10. 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 | SEL | input | Select input: SEL = 0 connects A and B to A0 and B0, SEL = 1 connects A and B to A1 and B1; the datasheet recommends pulling SEL to VCC or GND so it does not float. |
| 2 | A0 | bidirectional | Signal path port 0 I/O, which is bidirectional and has a signal-path I/O voltage limit of VCC + 0.3 V when VCC > 0 V. |
| 3 | A1 | bidirectional | Signal path port 1 I/O, which is bidirectional and has a signal-path I/O voltage limit of VCC + 0.3 V when VCC > 0 V. |
| 4 | A | bidirectional | Common signal path I/O, which connects to either A0 or A1 depending on SEL, with a continuous ON-state switch current limit of ±64 mA. |
| 5 | GND | power_in | Ground reference for the device; all voltages are referenced to ground. |
| 6 | B | bidirectional | Common signal path I/O, which connects to either B0 or B1 depending on SEL, with a continuous ON-state switch current limit of ±64 mA. |
| 7 | B1 | bidirectional | Signal path port 1 I/O, which is bidirectional and has a signal-path I/O voltage limit of 5.25 V when VCC = 0 V. |
| 8 | B0 | bidirectional | Signal path port 0 I/O, which is bidirectional and has a signal-path I/O voltage limit of 5.25 V when VCC = 0 V. |
| 9 | EN | input | Enable input: EN = 0 enables the switch and EN = 1 disables it (high impedance); control inputs support 1.8 V logic and the recommended high-level input at VCC = 4.3 V is 1.7 V minimum. |
| 10 | VCC | power_in | Supply voltage, recommended 3 V to 4.3 V with an absolute maximum of 7 V, and a bypass capacitor should be placed as close to this pin as possible. |
