ADUM1201BRZ-JSM from JSMSEMI, in a SOP-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 | Power supply for isolator side 1; operating range 2.5 V to 5.5 V (absolute maximum 6 V). |
| 2 | VIA | input | Logic signal input for channel A (side 1 → side 2); VIH ≥ 0.7 × VDD1, VIL ≤ 0.3 × VDD1. |
| 3 | GND1 | power_in | Ground reference for side 1; return current path for VDD1 supply and channel-A input logic. |
| 4 | VOB | output | Logic signal output for channel B (side 2 → side 1); defaults to logic high when VDD2 is unpowered. |
| 5 | VIB | input | Logic signal input for channel B (side 2 → side 1); VIH ≥ 0.7 × VDD2, VIL ≤ 0.3 × VDD2. |
| 6 | GND2 | power_in | Ground reference for side 2; return current path for VDD2 supply and channel-B input logic. |
| 7 | VOA | output | Logic signal output for channel A (side 1 → side 2); defaults to logic high when VDD1 is unpowered. |
| 8 | VDD2 | power_in | Power supply for isolator side 2; operating range 2.5 V to 5.5 V (absolute maximum 6 V). |
