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 | Y4 | bidirectional | Independent analog input/output channel 4. Switched to common Z when E=L and S2:S0 = 100. RON ~76 Ω @ VCC=4.5 V. |+| 2 | Y6 | bidirectional | Independent analog input/output channel 6. Switched to common Z when E=L and S2:S0 = 110. |+| 3 | Z | bidirectional | Common analog input/output. Connects to the selected Yn channel when E is LOW. |+| 4 | Y7 | bidirectional | Independent analog input/output channel 7. Switched to common Z when E=L and S2:S0 = 111. |+| 5 | Y5 | bidirectional | Independent analog input/output channel 5. Switched to common Z when E=L and S2:S0 = 101. |+| 6 | E | input | Active-LOW enable input. When LOW, one Yn (selected by S0-S2) connects to Z. When HIGH, all switches are in high-impedance OFF-state. |+| 7 | NC | unconnected | Not connected. Leave floating or tie for board layout convenience. |+| 8 | GND | power_in | Ground reference (0 V). |+| 9 | S2 | input | Digital channel-select input, MSB of the 3-bit channel address (S2:S1:S0). |+| 10 | S1 | input | Digital channel-select input, middle bit of the 3-bit channel address. |+| 11 | S0 | input | Digital channel-select input, LSB of the 3-bit channel address. |+| 12 | Y3 | bidirectional | Independent analog input/output channel 3. Switched to common Z when E=L and S2:S0 = 011. |+| 13 | Y0 | bidirectional | Independent analog input/output channel 0. Switched to common Z when E=L and S2:S0 = 000. |+| 14 | Y1 | bidirectional | Independent analog input/output channel 1. Switched to common Z when E=L and S2:S0 = 001. |+| 15 | Y2 | bidirectional | Independent analog input/output channel 2. Switched to common Z when E=L and S2:S0 = 010. |+| 16 | VCC | power_in | Positive supply voltage. Operating range 2.0 V to 6.0 V (74HC4851-Q100). Absolute max +7.0 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | TSSOP-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `74HC4851PW-Q100`+- `74HC4851PW-Q100D-Q100`+- `74HC4851PW-Q100BQ-Q100`++## CAD (KiCad official)++- Symbol: `74HC4851PW-Q100`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Nexperia datasheet](https://assets.nexperia.com/documents/data-sheet/74HC4851PW-Q100.pdf) (19 pp, sha256 `0b621ccffb78d38f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
