# ACPL-024L-500E

**Broadcom AVAGO** · Logic Output Optoisolators · SO-8

ACPL-024L-500E from Broadcom AVAGO, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Anode1 | passive | Anode of channel 1 input LED, driven through a current-limiting resistor with IF of 1.6 mA min. (2.2 mA recommended) and 8 mA max average. |
| 2 | Cathode1 | passive | Cathode of channel 1 input LED, on the input side of the isolation barrier. |
| 3 | Cathode2 | passive | Cathode of channel 2 input LED, on the input side of the isolation barrier. |
| 4 | Anode2 | passive | Anode of channel 2 input LED, driven through a current-limiting resistor with IF of 1.6 mA min. (2.2 mA recommended) and 8 mA max average. |
| 5 | GND | power_in | Output-side ground shared by both channels, with a 0.1 uF bypass capacitor required between VDD and GND. |
| 6 | VO2 | output | Channel 2 CMOS output, high when LED is on and low when off, with absolute max output current of 10 mA. |
| 7 | VO1 | output | Channel 1 CMOS output, high when LED is on and low when off, with absolute max output current of 10 mA. |
| 8 | VDD | power_in | Output-side supply for both channels, 2.7 V to 5.5 V recommended (6.5 V absolute max), with a 0.1 uF bypass capacitor to GND. |
