TMUX1109PWR from Texas Instruments, in a TSSOP-16-175mil. 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 | input | Address input line 0; 1.8V logic compatible (0 to 5.5V input range) controlling switch configuration. |
| 2 | EN | input | Active high enable input; 1.8V logic compatible (0 to 5.5V input range); all switches turned off when low. |
| 3 | VSS | power_in | Negative power supply rail; connect 0.1µF to 10µF decoupling capacitor between VSS and GND for reliable operation. |
| 4 | S1A | bidirectional | Source signal pin 1A; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 5 | S2A | bidirectional | Source signal pin 2A; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 6 | S3A | bidirectional | Source signal pin 3A; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 7 | S4A | bidirectional | Source signal pin 4A; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 8 | DA | bidirectional | Drain signal pin A; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 9 | DB | bidirectional | Drain signal pin B; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 10 | S4B | bidirectional | Source signal pin 4B; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 11 | S3B | bidirectional | Source signal pin 3B; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 12 | S2B | bidirectional | Source signal pin 2B; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 13 | S1B | bidirectional | Source signal pin 1B; rail-to-rail bidirectional signal path operating from VSS to VDD. |
| 14 | VDD | power_out | Positive power supply rail (1.08V to 5.5V single supply or +2.75V dual supply); connect 0.1µF to 10µF decoupling capacitor to GND. |
| 15 | GND | power_in | Ground reference at 0V potential. |
| 16 | A1 | input | Address input line 1; 1.8V logic compatible (0 to 5.5V input range) controlling switch configuration. |
