**Broadcom AVAGO** · Isolation Amplifiers · SO-8-6.8mm

ACPL-C87B-500E from Broadcom AVAGO, in a SO-8-6.8mm. 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. |

## 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)
- 3D model files: `acpl-c87b-500e-etched.step` / `acpl-c87b-500e-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `acpl-c87b-500e.step` / `acpl-c87b-500e.glb` are the bare package body.
