ADUM3201ARZ from Analog Devices, 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 | VDD1 | power_in | Supply voltage for isolator side 1, which must be 2.7 V to 5.5 V for the ADuM3201A grade, referenced to GND1. |
| 2 | VOA | output | Logic output A on side 1 of the ADuM3201, driven from the isolated channel A input (VIA, pin 7). |
| 3 | VIB | input | Logic input B on side 1 of the ADuM3201, which must stay within 0 V to VDD1 (VIL/VIH thresholds are 0.3 VDD1 and 0.7 VDD1). |
| 4 | GND1 | power_in | Ground 1, the ground reference point for the isolator side 1 supply and signals. |
| 5 | GND2 | power_in | Ground 2, the ground reference point for the isolator side 2 supply and signals. |
| 6 | VOB | output | Logic output B on side 2 of the ADuM3201, driven from the isolated channel B input (VIB, pin 3). |
| 7 | VIA | input | Logic input A on side 2 of the ADuM3201, which must stay within 0 V to VDD2 (VIL/VIH thresholds are 0.3 VDD2 and 0.7 VDD2). |
| 8 | VDD2 | power_in | Supply voltage for isolator side 2, which must be 2.7 V to 5.5 V for the ADuM3201A grade, referenced to GND2. |
