ISOW7841AQDWERQ1 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 | VCC | power_in | Primary-side supply voltage, referenced to GND1. |
| 2 | GND1 | power_in | Ground connection for VCC (primary side). |
| 3 | INA | input | Input channel A; logic input with VIH of 0.7 × VSI to VSI and VIL of 0 to 0.3 × VSI. |
| 4 | INB | input | Input channel B; logic input with VIH of 0.7 × VSI to VSI and VIL of 0 to 0.3 × VSI. |
| 5 | INC | input | Input channel C; logic input with VIH of 0.7 × VSI to VSI and VIL of 0 to 0.3 × VSI. |
| 6 | OUTD | output | Output channel D. |
| 7 | NC | unconnected | Not connected. |
| 8 | GND1 | power_in | Ground connection for VCC (primary side). |
| 9 | GND2 | power_in | Ground connection for VISO (isolated side). |
| 10 | SEL | input | VISO selection pin: VISO = 5 V when SEL is shorted to VISO; VISO = 3.3 V when SEL is shorted to GND2 or left floating. |
| 11 | IND | input | Input channel D; logic input with VIH of 0.7 × VSI to VSI and VIL of 0 to 0.3 × VSI. |
| 12 | OUTC | output | Output channel C. |
| 13 | OUTB | output | Output channel B. |
| 14 | OUTA | output | Output channel A. |
| 15 | GND2 | power_in | Ground connection for VISO (isolated side). |
| 16 | VISO | power_out | Isolated supply voltage output, set to 5 V or 3.3 V by the SEL pin. |
