Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | Z | bidirectional | Common analog input/output (the shared pole of the SP16T switch). Connects to whichever Y0..Y15 channel is selected by S0..S3 when E is LOW. |+| 2 | Y7 | bidirectional | Independent analog input/output channel 7. Routed to Z when S3..S0 = 0111 and E is LOW. |+| 3 | Y6 | bidirectional | Independent analog input/output channel 6. Routed to Z when S3..S0 = 0110 and E is LOW. |+| 4 | Y5 | bidirectional | Independent analog input/output channel 5. Routed to Z when S3..S0 = 0101 and E is LOW. |+| 5 | Y4 | bidirectional | Independent analog input/output channel 4. Routed to Z when S3..S0 = 0100 and E is LOW. |+| 6 | Y3 | bidirectional | Independent analog input/output channel 3. Routed to Z when S3..S0 = 0011 and E is LOW. |+| 7 | Y2 | bidirectional | Independent analog input/output channel 2. Routed to Z when S3..S0 = 0010 and E is LOW. |+| 8 | Y1 | bidirectional | Independent analog input/output channel 1. Routed to Z when S3..S0 = 0001 and E is LOW. |+| 9 | Y0 | bidirectional | Independent analog input/output channel 0. Routed to Z when S3..S0 = 0000 and E is LOW. |+| 10 | S0 | input | Address input bit 0 (LSB) of the 4-bit channel-select bus. Together with S1..S3 selects which Y channel connects to Z. CMOS-level input on 74HC4067. |+| 11 | S1 | input | Address input bit 1 of the 4-bit channel-select bus. CMOS-level input on 74HC4067. |+| 12 | GND | power_in | Ground reference (0 V) for the device. |+| 13 | S3 | input | Address input bit 3 (MSB) of the 4-bit channel-select bus. CMOS-level input on 74HC4067. |+| 14 | S2 | input | Address input bit 2 of the 4-bit channel-select bus. CMOS-level input on 74HC4067. |+| 15 | E | input | Active-LOW enable input. When LOW the selected switch is ON; when HIGH all 16 switches are OFF (device disabled). CMOS-level input on 74HC4067. |+| 16 | Y15 | bidirectional | Independent analog input/output channel 15. Routed to Z when S3..S0 = 1111 and E is LOW. |+| 17 | Y14 | bidirectional | Independent analog input/output channel 14. Routed to Z when S3..S0 = 1110 and E is LOW. |+| 18 | Y13 | bidirectional | Independent analog input/output channel 13. Routed to Z when S3..S0 = 1101 and E is LOW. |+| 19 | Y12 | bidirectional | Independent analog input/output channel 12. Routed to Z when S3..S0 = 1100 and E is LOW. |+| 20 | Y11 | bidirectional | Independent analog input/output channel 11. Routed to Z when S3..S0 = 1011 and E is LOW. |+| 21 | Y10 | bidirectional | Independent analog input/output channel 10. Routed to Z when S3..S0 = 1010 and E is LOW. |+| 22 | Y9 | bidirectional | Independent analog input/output channel 9. Routed to Z when S3..S0 = 1001 and E is LOW. |+| 23 | Y8 | bidirectional | Independent analog input/output channel 8. Routed to Z when S3..S0 = 1000 and E is LOW. |+| 24 | VCC | power_in | Positive supply voltage. Operating range 2.0 V to 10.0 V (74HC4067) or 4.5 V to 5.5 V (74HCT4067). Absolute maximum 11.0 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | TSSOP-24 |+| Category | Interface |+| Pins | 24 |++## Ordering variants++Same part, different packaging or reel option.++- `74HC4067PW`+- `74HC4067PWD`+- `74HC4067PWBQ`++## CAD (KiCad official)++- Symbol: `74HC4067PW`+- Footprint: `Package_SO:TSSOP-24_4.4x7.8mm_P0.65mm`+- 3D model: TSSOP-24 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Nexperia datasheet](https://assets.nexperia.com/documents/data-sheet/74HC4067PW.pdf) (26 pp, sha256 `043c703e78310137`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
