ISO7720DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC1 | power_in | Input-side power supply, 2.25 V to 5.5 V nominal with integrated UVLO threshold at 2.25 V rising |
| 2 | INA | input | Digital logic input for isolation channel A, accepts 0 V to VCCI levels with 0.7×VCCI high threshold |
| 3 | INB | input | Digital logic input for isolation channel B, accepts 0 V to VCCI levels with 0.7×VCCI high threshold |
| 4 | GND1 | power_in | Ground reference for input-side supply and signals, connected to VCC1 |
| 5 | GND2 | power_in | Ground reference for output-side supply and signals, connected to VCC2 across isolation barrier |
| 6 | OUTB | output | Isolated digital output for channel B, sources/sinks ±4 mA at 5 V VCC2 with 11 ns typical propagation delay |
| 7 | OUTA | output | Isolated digital output for channel A, sources/sinks ±4 mA at 5 V VCC2 with 11 ns typical propagation delay |
| 8 | VCC2 | power_in | Output-side power supply, 2.25 V to 5.5 V nominal with integrated UVLO threshold at 2.25 V rising |
