MUX36D08IRTVR from Texas Instruments, in a TQFN-32-EP(5x5). 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 | S8B | passive | Source pin 8B of the B-side channel set; can be an input or output. |
| 2 | S7B | passive | Source pin 7B; can be an input or output. |
| 3 | S6B | passive | Source pin 6B; can be an input or output. |
| 4 | S5B | passive | Source pin 5B; can be an input or output. |
| 5 | S4B | passive | Source pin 4B; can be an input or output. |
| 6 | S3B | passive | Source pin 3B; can be an input or output. |
| 7 | S2B | passive | Source pin 2B; can be an input or output. |
| 8 | S1B | passive | Source pin 1B; can be an input or output. |
| 9 | GND | power_in | Ground (0 V) reference for the device. |
| 10 | A2 | input | Digital address line 2 that selects the switch pair when EN is high; address voltage must stay between VSS and VDD. |
| 11 | NC | unconnected | No connect; do not connect. |
| 12 | NC | unconnected | No connect; do not connect. |
| 13 | NC | unconnected | No connect; do not connect. |
| 14 | A1 | input | Digital address line 1 that selects the switch pair when EN is high; address voltage must stay between VSS and VDD. |
| 15 | A0 | input | Digital address line 0 that selects the switch pair when EN is high; address voltage must stay between VSS and VDD. |
| 16 | EN | input | Active high enable; when low all switches are off, and when high the A[2:0] inputs select which pair of switches is on; EN must stay between VSS and VDD. |
| 17 | S1A | passive | Source pin 1A; can be an input or output. |
| 18 | S2A | passive | Source pin 2A; can be an input or output. |
| 19 | S3A | passive | Source pin 3A; can be an input or output. |
| 20 | S4A | passive | Source pin 4A; can be an input or output. |
| 21 | S5A | passive | Source pin 5A; can be an input or output. |
| 22 | S6A | passive | Source pin 6A; can be an input or output. |
| 23 | S7A | passive | Source pin 7A; can be an input or output. |
| 24 | S8A | passive | Source pin 8A; can be an input or output. |
| 25 | VSS | power_in | Negative power supply, the most negative supply potential; can be tied to ground in single-supply use and needs a 0.1 µF to 10 µF decoupling capacitor to GND. |
| 26 | NC | unconnected | No connect; do not connect. |
| 27 | DA | passive | Drain pin A; can be an input or output. |
| 28 | NC | unconnected | No connect; do not connect. |
| 29 | VDD | power_in | Positive power supply, the most positive supply potential; operating range is 10 V to 36 V single supply or ±5 V to ±18 V dual supply, with a 0.1 µF to 10 µF decoupling capacitor to GND. |
| 30 | NC | unconnected | No connect; do not connect. |
| 31 | DB | passive | Drain pin B; can be an input or output. |
| 32 | NC | unconnected | No connect; do not connect. |
| 33 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
