MUX506IDWR from Texas Instruments, in a SOIC-28-300mil. 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 | VDD | power_in | Positive power supply; most positive power-supply potential; connect 0.1 µF to 10 µF decoupling capacitor between VDD and GND. |
| 2 | NC | unconnected | No connect; do not connect. |
| 3 | NC | unconnected | No connect; do not connect. |
| 4 | S16 | bidirectional | Source pin 16 for 16:1 multiplexer operation; can be input or output. |
| 5 | S15 | bidirectional | Source pin 15 for 16:1 multiplexer operation; can be input or output. |
| 6 | S14 | bidirectional | Source pin 14 for 16:1 multiplexer operation; can be input or output. |
| 7 | S13 | bidirectional | Source pin 13 for 16:1 multiplexer operation; can be input or output. |
| 8 | S12 | bidirectional | Source pin 12 for 16:1 multiplexer operation; can be input or output. |
| 9 | S11 | bidirectional | Source pin 11 for 16:1 multiplexer operation; can be input or output. |
| 10 | S10 | bidirectional | Source pin 10 for 16:1 multiplexer operation; can be input or output. |
| 11 | S9 | bidirectional | Source pin 9 for 16:1 multiplexer operation; can be input or output. |
| 12 | GND | power_in | Ground (0 V) reference for power supply. |
| 13 | NC | unconnected | No connect; do not connect. |
| 14 | A3 | input | Digital input address line 3 for channel selection in 16:1 multiplexer. |
| 15 | A2 | input | Digital input address line 2 for channel selection in 16:1 multiplexer. |
| 16 | A1 | input | Digital input address line 1 for channel selection in 16:1 multiplexer. |
| 17 | A0 | input | Digital input address line 0 for channel selection in 16:1 multiplexer. |
| 18 | EN | input | Active high digital enable input; when low, all switches are turned off; when high, A[3:0] determines which switch is on. |
| 19 | S1 | bidirectional | Source pin 1 for 16:1 multiplexer operation; can be input or output. |
| 20 | S2 | bidirectional | Source pin 2 for 16:1 multiplexer operation; can be input or output. |
