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 | CH4 | bidirectional | Channel 4 in/out. Analog signal path to/from COM when address A/B/C = 100 and INH = 0. rON typ 125 Ω at VDD=15V. |+| 2 | CH6 | bidirectional | Channel 6 in/out. Analog signal path to/from COM when address A/B/C = 110 and INH = 0. |+| 3 | COM | bidirectional | Common out/in. Bidirectional analog common terminal connected to the selected channel (CH0-CH7) when INH = 0. |+| 4 | CH7 | bidirectional | Channel 7 in/out. Analog signal path to/from COM when address A/B/C = 111 and INH = 0. |+| 5 | CH5 | bidirectional | Channel 5 in/out. Analog signal path to/from COM when address A/B/C = 101 and INH = 0. |+| 6 | INH | input | Inhibit input. When high, disables all channels (all switches OFF). When low, the channel selected by A/B/C is connected to COM. Digital logic input referenced to VSS/VDD; VIH ≥ 11V at VDD=15V. |+| 7 | VEE | power_in | Negative analog supply input. Sets the lower bound of the analog signal range. For single-supply operation tie to VSS; for dual-supply operation typically −5V to −10V. VDD−VEE ≤ 20V. |+| 8 | VSS | power_in | Ground / digital logic reference. Reference for the A/B/C/INH digital control inputs. |+| 9 | C | input | Channel select C (MSB of the 3-bit channel address). Digital logic input; combined with A and B selects one of CH0-CH7 when INH = 0. |+| 10 | B | input | Channel select B (middle bit of the 3-bit channel address). Digital logic input. |+| 11 | A | input | Channel select A (LSB of the 3-bit channel address). Digital logic input. |+| 12 | CH3 | bidirectional | Channel 3 in/out. Analog signal path to/from COM when address A/B/C = 011 and INH = 0. |+| 13 | CH0 | bidirectional | Channel 0 in/out. Analog signal path to/from COM when address A/B/C = 000 and INH = 0. |+| 14 | CH1 | bidirectional | Channel 1 in/out. Analog signal path to/from COM when address A/B/C = 001 and INH = 0. |+| 15 | CH2 | bidirectional | Channel 2 in/out. Analog signal path to/from COM when address A/B/C = 010 and INH = 0. |+| 16 | VDD | power_in | Positive supply input. 3V to 20V referenced to VSS. Also serves as the digital-input high reference (VIH ≥ 0.7·VDD). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `CD4051BPWR`+- `CD4051BPWRE`+- `CD4051BPWRJ`+- `CD4051BPWRM`+- `CD4051BPWRNS`++## CAD (KiCad official)++- Symbol: `CD4051BPWR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/cd4051b.pdf) (39 pp, sha256 `c234939dccf18398`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
