ACPL-C790-500E 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	Input-side supply voltage, 4.5 V to 5.5 V referenced to GND1. Requires a 0.1 µF bypass capacitor between pins 1 and 4. Typical input-side supply current IDD1 = 11 mA (18.5 mA max).
2	VIN+	input	Positive analog input. Nominal input range ±200 mV (full-scale ±300 mV, functional ±2 V) relative to VIN-. Input bias current typ. -0.1 µA; single-ended input impedance 27 kΩ.
3	VIN-	input	Negative analog input, normally connected to GND1 for single-ended sensing. Same ±200 mV nominal range and 27 kΩ single-ended input impedance as VIN+.
4	GND1	power_in	Input-side ground reference for VDD1, VIN+ and VIN-.
5	GND2	power_in	Output-side ground reference for VDD2, VOUT+ and VOUT-. Galvanically isolated from GND1 by the optical barrier (VIORM = 1414 Vpeak, 5000 Vrms/1 min).
6	VOUT-	output	Negative differential analog output. Output common-mode voltage 1.23 V, output voltage range 0 V to 2.5 V, output resistance ~21 Ω, short-circuit current ~11 mA.
7	VOUT+	output	Positive differential analog output. Output common-mode voltage 1.23 V, output voltage range 0 V to 2.5 V, output resistance ~21 Ω, short-circuit current ~11 mA.
8	VDD2	power_in	Output-side supply voltage, 3 V to 5.5 V referenced to GND2. Requires a 0.1 µF bypass capacitor between pins 5 and 8. Typical IDD2 = 7 mA at 5 V (6.8 mA at 3.3 V).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`acpl-c790-500e.step`	122 KB	You want the bare part, or you mark your own boards.
`acpl-c790-500e-etched.step`	2.5 MB	You want the part with `ACPL-C790-500E` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 618 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
