ISO7720DWVR 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 voltage 2.25V-5.5V with 0.1µF bypass capacitor to GND1. |
| 2 | INA | input | Channel A CMOS input with high threshold 0.7×VCCI, low threshold 0.3×VCCI, and maximum input current ±10µA. |
| 3 | INB | input | Channel B CMOS input with high threshold 0.7×VCCI, low threshold 0.3×VCCI, and maximum input current ±10µA. |
| 4 | GND1 | power_in | Input side ground reference and return path for VCC1 and signal inputs. |
| 5 | GND2 | power_in | Output side ground reference isolated from GND1 by 5000VRMS SiO2 capacitive barrier in DWV package. |
| 6 | OUTB | output | Channel B digital output with high level ≥4.6V and low level ≤0.4V at 5V supply, typical propagation delay 11ns. |
| 7 | OUTA | output | Channel A digital output with high level ≥4.6V and low level ≤0.4V at 5V supply, typical propagation delay 11ns. |
| 8 | VCC2 | power_in | Output side power supply voltage 2.25V-5.5V independent of VCC1 with 0.1µF bypass capacitor to GND2. |
