Bilateral I/O of switch 1 (paired with 1Z). Signal range 0 V to VDD. |+| 2 | 1Z | bidirectional | Analog switch 1 terminal Z. Bilateral I/O of switch 1 (paired with 1Y). |+| 3 | 2Z | bidirectional | Analog switch 2 terminal Z. Bilateral I/O of switch 2 (paired with 2Y). |+| 4 | 2Y | bidirectional | Analog switch 2 terminal Y. Bilateral I/O of switch 2 (paired with 2Z). |+| 5 | 2E | input | Enable input for switch 2 (active HIGH). HIGH closes the switch; LOW opens it. VIH ≥ 3.5 V @ VDD=5 V; VIL ≤ 1.5 V @ VDD=5 V. |+| 6 | 3E | input | Enable input for switch 3 (active HIGH). HIGH closes the switch; LOW opens it. |+| 7 | VSS | power_in | Ground reference (0 V). Negative supply / substrate return. |+| 8 | 3Y | bidirectional | Analog switch 3 terminal Y. Bilateral I/O of switch 3 (paired with 3Z). |+| 9 | 3Z | bidirectional | Analog switch 3 terminal Z. Bilateral I/O of switch 3 (paired with 3Y). |+| 10 | 4Z | bidirectional | Analog switch 4 terminal Z. Bilateral I/O of switch 4 (paired with 4Y). |+| 11 | 4Y | bidirectional | Analog switch 4 terminal Y. Bilateral I/O of switch 4 (paired with 4Z). |+| 12 | 4E | input | Enable input for switch 4 (active HIGH). HIGH closes the switch; LOW opens it. |+| 13 | 1E | input | Enable input for switch 1 (active HIGH). HIGH closes the switch; LOW opens it. |+| 14 | VDD | power_in | Positive supply voltage, 3 V to 9 V recommended (absolute max +12 V). Decouple to VSS with a local ceramic capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | lingxingic CD4066BM LX |+| Package | SOP-14 |+| Category | Interface |+| Pins | 14 |++## Ordering variants++- `CD4066BM(LX)`+- `CD4066BMCD4066BE(LX)`+- `CD4066BMCD4066BPW(LX)`++## CAD (KiCad official)++- Symbol: `CD4066BM`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [lingxingic CD4066BM LX datasheet](docs/cd4066bm-datasheet.pdf) (14 pp, sha256 `c719e5f4a019aa91`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
