# ACPL-M61M-000E

**Broadcom Limited** · Logic Output Optocoupler · SOIC-5-175mil

ACPL-M61M-000E from Broadcom Limited, in a SOIC-5-175mil. 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 | Anode | input | LED anode, driven through a series limiting resistor with recommended high-level input current of 1.6 mA min to 3.2 mA max and an absolute maximum average forward current of 8 mA. |
| 3 | Cathode | passive | LED cathode, with a maximum reverse input voltage of 5 V and a typical forward voltage of 1.33 V at IF = 2 mA. |
| 4 | GND | power_in | Output-side ground, with a 0.1 uF bypass capacitor to VDD placed as close as possible and no more than 3 mm from the power pins. |
| 5 | Vo | output | CMOS output that is low when the LED is ON and high when it is OFF, with an absolute maximum output current of 10 mA and an output voltage range of -0.5 V to VDD + 0.4 V. |
| 6 | VDD | power_in | Output-side supply with a recommended range of 2.25 V to 3.6 V (absolute maximum 4 V), requiring a 0.1 uF bypass capacitor to GND placed as close as possible. |
