ISO7220BDR 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 channels; 3.0-5.5V recommended; typical quiescent current 1-2mA. |
| 2 | INA | input | 5V tolerant TTL/CMOS input channel A; minimum high threshold 2.0V, maximum low threshold 0.8V. |
| 3 | INB | input | 5V tolerant TTL/CMOS input channel B; minimum high threshold 2.0V, maximum low threshold 0.8V. |
| 4 | GND1 | power_in | Ground reference for input-side supply (VCC1). |
| 5 | GND2 | power_in | Ground reference for output-side supply (VCC2). |
| 6 | OUTB | output | 4mA CMOS output channel B; low level 0.2-0.4V, high level VCC−0.8V minimum to 4.6V maximum at 4mA source. |
| 7 | OUTA | output | 4mA CMOS output channel A; low level 0.2-0.4V, high level VCC−0.8V minimum to 4.6V maximum at 4mA source. |
| 8 | VCC2 | power_in | Power supply for output-side channels; 3.0-5.5V recommended; typical quiescent current 16-31mA. |
