Signal passes between 1A and 1B when control input 1C is high. Signal amplitude up to 5.5 V (peak). |+| 2 | 1B | bidirectional | Input/Output terminal B of analog switch channel 1. Bilateral pair with 1A; on-resistance typ 29 Ω at VCC=3 V (150 Ω max). |+| 3 | 2B | bidirectional | Input/Output terminal B of analog switch channel 2. Connects to 2A when 2C is high. |+| 4 | 2A | bidirectional | Input/Output terminal A of analog switch channel 2. Bilateral pair with 2B. |+| 5 | 2C | input | Control input for channel 2. Switch is ON when this pin is at logic high; OFF when low. Logic input voltage range 0-5.5 V; VIH = VCC×0.7 typical. |+| 6 | 3C | input | Control input for channel 3. Switch is ON when this pin is at logic high; OFF when low. |+| 7 | GND | power_in | Ground (0 V) reference for the device. |+| 8 | 3A | bidirectional | Input/Output terminal A of analog switch channel 3. Connects to 3B when 3C is high. |+| 9 | 3B | bidirectional | Input/Output terminal B of analog switch channel 3. Bilateral pair with 3A. |+| 10 | 4B | bidirectional | Input/Output terminal B of analog switch channel 4. Connects to 4A when 4C is high. |+| 11 | 4A | bidirectional | Input/Output terminal A of analog switch channel 4. Bilateral pair with 4B. |+| 12 | 4C | input | Control input for channel 4. Switch is ON when this pin is at logic high; OFF when low. |+| 13 | 1C | input | Control input for channel 1. Switch is ON when this pin is at logic high; OFF when low. |+| 14 | VCC | power_in | Positive supply, 1.65 V to 5.5 V (7 V absolute max). Bypass to GND with a 0.1 µF to 10 µF decoupling capacitor for reliable operation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-14 |+| Category | Interface |+| Pins | 14 |++## Ordering variants++- `SN74LV4066ADR`+- `SN74LV4066ADRD`+- `SN74LV4066ADRPW`+- `SN74LV4066ADRPWR`+- `SN74LV4066ADRRGY`+- `SN74LV4066ADRRGYR`++## CAD (KiCad official)++- Symbol: `SN74LV4066ADR`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-14 (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/sn74lv4066a.pdf) (37 pp, sha256 `4fd892bfeb726fef`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
