ISO7220AQDRQ1 from Texas Instruments, in a SOIC-8. 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 input-side isolation channel, rated 2.8V to 5.5V. |
| 2 | INA | input | Digital input for channel A, accepts TTL/CMOS logic levels with maximum low 0.8V and minimum high 2V. |
| 3 | INB | input | Digital input for channel B, accepts TTL/CMOS logic levels with maximum low 0.8V and minimum high 2V. |
| 4 | GND1 | power_in | Ground reference for input-side power supply (VCC1). |
| 5 | GND2 | power_in | Ground reference for output-side power supply (VCC2). |
| 6 | OUTB | output | Digital output for channel B, source or sink capability ±4mA at recommended operating conditions. |
| 7 | OUTA | output | Digital output for channel A, source or sink capability ±4mA at recommended operating conditions. |
| 8 | VCC2 | power_in | Power supply for output-side isolation channel, rated 2.8V to 5.5V. |
