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 | 1Y | bidirectional | Switch 1 analog I/O terminal Y. Bidirectional analog signal path; connects to 1Z through the switch when 1E is HIGH. Input voltage range 0 V to VDD (VDD = 3-9 V). |+| 2 | 1Z | bidirectional | Switch 1 analog I/O terminal Z. Bidirectional analog signal path; connects to 1Y through the switch when 1E is HIGH. Typical RON ~80 Ω at VDD=9 V. |+| 3 | 2Z | bidirectional | Switch 2 analog I/O terminal Z. Bidirectional analog signal path; connects to 2Y through the switch when 2E is HIGH. |+| 4 | 2Y | bidirectional | Switch 2 analog I/O terminal Y. Bidirectional analog signal path; connects to 2Z through the switch when 2E is HIGH. |+| 5 | 2E | input | Switch 2 enable input, active HIGH. HIGH turns switch 2 ON (2Y-2Z conducts); LOW turns it OFF. VIH ≥ 3.5 V at VDD=5 V, ≥ 7 V at VDD=9 V. |+| 6 | 3E | input | Switch 3 enable input, active HIGH. HIGH turns switch 3 ON (3Y-3Z conducts); LOW turns it OFF. |+| 7 | VSS | power_in | Ground (0 V) reference for the device. Analog input voltage range is referenced from VSS to VDD. |+| 8 | 3Y | bidirectional | Switch 3 analog I/O terminal Y. Bidirectional analog signal path; connects to 3Z through the switch when 3E is HIGH. |+| 9 | 3Z | bidirectional | Switch 3 analog I/O terminal Z. Bidirectional analog signal path; connects to 3Y through the switch when 3E is HIGH. |+| 10 | 4Z | bidirectional | Switch 4 analog I/O terminal Z. Bidirectional analog signal path; connects to 4Y through the switch when 4E is HIGH. |+| 11 | 4Y | bidirectional | Switch 4 analog I/O terminal Y. Bidirectional analog signal path; connects to 4Z through the switch when 4E is HIGH. |+| 12 | 4E | input | Switch 4 enable input, active HIGH. HIGH turns switch 4 ON (4Y-4Z conducts); LOW turns it OFF. |+| 13 | 1E | input | Switch 1 enable input, active HIGH. HIGH turns switch 1 ON (1Y-1Z conducts); LOW turns it OFF. |+| 14 | VDD | power_in | Positive supply voltage. Recommended operating range 3 V to 9 V (absolute max +12 V referenced to VSS). Sets the upper analog input range and the logic threshold for the nE control inputs. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XBLW CD4066BDTR XBLW |+| Package | SOP-14 |+| Category | Interface |+| Pins | 14 |++## Ordering variants++- `CD4066BDTR`+- `CD4066BDTRBE`+- `CD4066BDTRBTDTR`++## CAD (KiCad official)++- Symbol: `CD4066BDTR`+- 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:** [XBLW CD4066BDTR XBLW datasheet](docs/cd4066bdtr-datasheet.pdf) (None pp, sha256 `11f1b15b0d4d1b15`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
