TMUX1574RSVR from Texas Instruments, in a UQFN-16(1.8x2.6). 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 | S1B | bidirectional | Source pin 1B; bidirectional signal path supporting analog and digital signals. |
| 2 | D1 | bidirectional | Drain pin 1; bidirectional signal path supporting analog and digital signals. |
| 3 | S2A | bidirectional | Source pin 2A; bidirectional signal path supporting analog and digital signals. |
| 4 | S2B | bidirectional | Source pin 2B; bidirectional signal path supporting analog and digital signals. |
| 5 | D2 | bidirectional | Drain pin 2; bidirectional signal path supporting analog and digital signals. |
| 6 | GND | power_in | Ground (0 V) reference. |

Package_DFN_QFN:UQFN-16_1.8x2.6mm_P0.4mm - 3D model: UQFN-16(1.8x2.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal UFQFPN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
