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 | /BE1 | input | Active-LOW switch enable for channel 1. Drive low to close the A1<->B1 FET switch; drive high to place A1/B1 into Hi-Z. TTL/CMOS input, tolerant to 3.6V regardless of VCC. |+| 2 | A1 | passive | Bus A, channel 1. Bidirectional pass-FET terminal connected to B1 when /BE1 is low; Hi-Z otherwise. ~5Ω on-resistance, high-bandwidth (>400 MHz), 5V tolerant. |+| 3 | B1 | passive | Bus B, channel 1. Bidirectional pass-FET terminal connected to A1 when /BE1 is low; Hi-Z otherwise. ~5Ω on-resistance, 5V tolerant. |+| 4 | GND | power_in | Ground reference (0 V) for logic and switch bias. |+| 5 | A2 | passive | Bus A, channel 2. Bidirectional pass-FET terminal connected to B2 when /BE2 is low; Hi-Z otherwise. ~5Ω on-resistance, 5V tolerant. |+| 6 | B2 | passive | Bus B, channel 2. Bidirectional pass-FET terminal connected to A2 when /BE2 is low; Hi-Z otherwise. ~5Ω on-resistance, 5V tolerant. |+| 7 | /BE2 | input | Active-LOW switch enable for channel 2. Drive low to close the A2<->B2 FET switch; drive high to place A2/B2 into Hi-Z. TTL/CMOS input, tolerant to 3.6V regardless of VCC. |+| 8 | VCC | power_in | Positive supply, 2.5V or 3.3V (±10%). Absolute max 4.6V to GND. Datasheet recommends applying VCC before driving signals on any I/O or control pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | MSOP-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `PI3C3306UEX`+- `PI3C3306UEXLEX`+- `PI3C3306UEXLE`++## CAD (KiCad official)++- Symbol: `PI3C3306UEX`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/PI3C3306UEX.pdf) (8 pp, sha256 `d69913023e82fa86`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
