ADUM5242ARZ-RL7 from Analog Devices, 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 | VDD | power_in | Primary side power supply voltage, 4.5 to 5.5 V when DC-DC enabled or 2.7 to 4.0 V when DC-DC disabled |
| 2 | VOA | output | Logic Output A, output voltage swing 0 V to VDD referenced to GND |
| 3 | VOB | input | Logic Input B, input threshold VIH = 0.7 × VDD, VIL = 0.3 × VDD |
| 4 | GND | power_in | Primary side ground reference |
| 5 | GNDISO | power_in | Secondary side isolated ground reference |
| 6 | VIB | output | Logic Output B, output voltage swing 0 V to VISO referenced to GNDISO |
| 7 | VIA | input | Logic Input A, input threshold VIH = 0.7 × VISO, VIL = 0.3 × VISO |
| 8 | VISO | power_out | Secondary side isolated power supply voltage, 4.5 to 5.5 V output (DC-DC enabled) or 2.7 to 5.5 V input (DC-DC disabled), 10 mA maximum output current |
