TLP2345 from TOSHIBA, in a SO-5. 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 | Anode | input | LED Anode input; maximum forward current 15 mA, forward voltage 1.35-1.65 V at IF=3 mA. |
| 2 | NC | unconnected | Not connected; undocumented on this SO6 package variant. |
| 3 | Cathode | passive | LED Cathode; return path for LED input current with maximum reverse voltage ±50 V. |
| 4 | GND | power_in | Ground reference for output stage; bypass capacitor 0.1 µF to pin 6 required within 1 cm for stable operation. |
| 5 | VO | output | Photo detector output from totem-pole stage with source and sink capability; voltage range 0-0.2 V (low) to VCC-0.4 V (high). |
| 6 | VCC | power_in | Positive supply voltage for output stage; rated 4.5-30 V with maximum quiescent current 3 mA. |
