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 | VDD1 | power_in | Supply voltage for the input (isolated) side, 4.5V to 5.5V, referenced to GND1. A 0.1-µF bypass capacitor must be connected between pins 1 and 4. |+| 2 | VIN | input | Analog voltage input, referenced to GND1. Nominal input range 0 to 2V (full-scale 2.46V). Equivalent input impedance ~1 GΩ. |+| 3 | SHDN | input | Shutdown pin, active high. When asserted (VDD1-0.5V to VDD1), reduces input-side supply current IDD1 to ~15 µA. VIL max 0.8V. |+| 4 | GND1 | power_in | Input-side ground reference for VDD1, VIN, and SHDN. |+| 5 | GND2 | power_in | Output-side ground reference for VDD2, VOUT+, and VOUT-. |+| 6 | VOUT- | output | Negative differential analog output, referenced to GND2. Common-mode output voltage ~1.23V, output resistance ~36 Ω. |+| 7 | VOUT+ | output | Positive differential analog output, referenced to GND2. Common-mode output voltage ~1.23V, output resistance ~36 Ω. |+| 8 | VDD2 | power_in | Supply voltage for the output (isolated) side, 3.0V to 5.5V, referenced to GND2. A 0.1-µF bypass capacitor must be connected between pins 5 and 8. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Broadcom AVAGO |+| Package | SO-8-6.8mm |+| Category | Signal Isolation Devices |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `ACPL-C87B-500E`+- `ACPL-C87B-500E-000E`++## CAD (KiCad official)++- Symbol: `ACPL-C87B-500E`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8-6.8mm (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Broadcom AVAGO datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588906395865657344) (16 pp, sha256 `9828a505b30e5f86`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
