ISO7340CQDWQ1 from Texas Instruments, in a SOIC-16-300mil. 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 | VCC1 | power_in | Power supply for the side-1 input circuitry; the recommended supply range for VCC1 and VCC2 is 3 V to 5.5 V. |
| 2 | GND1 | power_in | Ground connection for VCC1 (side-1 ground). |
| 3 | INA | input | Input for channel A, forwarded to OUTA across the isolation barrier. |
| 4 | INB | input | Input for channel B, forwarded to OUTB across the isolation barrier. |
| 5 | INC | input | Input for channel C, forwarded to OUTC across the isolation barrier. |
| 6 | IND | input | Input for channel D, forwarded to OUTD across the isolation barrier. |
| 7 | NC | unconnected | No connect; the pin is floating with no internal connection. |
| 8 | GND1 | power_in | Ground connection for VCC1 (side-1 ground). |
| 9 | GND2 | power_in | Ground connection for VCC2 (side-2 ground). |
| 10 | EN | input | Output enable; all output pins are enabled when EN is high or disconnected and disabled when EN is low. |
| 11 | OUTD | output | Output for channel D, driven on the side-2 output supply (VCC2). |
| 12 | OUTC | output | Output for channel C, driven on the side-2 output supply (VCC2). |
| 13 | OUTB | output | Output for channel B, driven on the side-2 output supply (VCC2). |
| 14 | OUTA | output | Output for channel A, driven on the side-2 output supply (VCC2). |
| 15 | GND2 | power_in | Ground connection for VCC2 (side-2 ground). |
| 16 | VCC2 | power_in | Power supply for the side-2 output circuitry; the recommended supply range for VCC1 and VCC2 is 3 V to 5.5 V. |
