**Texas Instruments** · Digital Isolators · SOIC-16

ISO7810DW from Texas Instruments, in a SOIC-16. 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 | GND1 | power_in | Ground connection for VCC1 primary side of the isolation barrier. |
| 2 | NC | unconnected | No internal connection. |
| 3 | VCC1 | power_in | Primary side power supply, 2.25V to 5.5V operating range. |
| 4 | IN | input | Input channel with high level threshold 0.7×VCC1 and low level threshold 0.3×VCC1, input pulse duration minimum 7ns. |
| 5 | NC | unconnected | No internal connection. |
| 6 | NC | unconnected | No internal connection. |
| 7 | GND1 | power_in | Ground connection for VCC1 primary side of the isolation barrier. |
| 8 | NC | unconnected | No internal connection. |
| 9 | GND2 | power_in | Ground connection for VCC2 secondary side of the isolation barrier. |
| 10 | NC | unconnected | No internal connection. |
| 11 | NC | unconnected | No internal connection. |
| 12 | NC | unconnected | No internal connection. |
| 13 | OUT | output | Output channel with high level voltage VCC2-0.4V to VCC2-0.2V at IOH=-4mA (5V supply) and low level voltage 0.2V to 0.4V at IOL=4mA (5V supply). |
| 14 | VCC2 | power_in | Secondary side power supply, 2.25V to 5.5V operating range, isolated from primary side. |
| 15 | NC | unconnected | No internal connection. |
| 16 | GND2 | power_in | Ground connection for VCC2 secondary side of the isolation barrier. |
