ISO35MDWR from Texas Instruments, in a SOIC-16-300mil. 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 | VCC1 | power_in | Logic side power supply pin for side 1 of the isolator. |
| 2 | GND1 | power_in | Logic side ground, internally connected to pins 7 and 8. |
| 3 | R | output | Receiver output. |
| 4 | RE | input | Receiver logic-low enable input. |
| 5 | DE | input | Driver logic-high enable input. |
| 6 | D | input | Driver input. |
| 7 | GND1 | power_in | Logic side ground, internally connected to pins 2 and 8. |
| 8 | GND1 | power_in | Logic side ground, internally connected to pins 2 and 7. |
| 9 | GND2 | power_in | Bus side ground, internally connected to pins 10 and 15. |
| 10 | GND2 | power_in | Bus side ground, internally connected to pins 9 and 15. |
| 11 | Y | output | Noninverting bus output (ISO35x only; this pin is NC on the ISO15x). |
| 12 | Z | output | Inverting bus output (ISO35x only; this pin is NC on the ISO15x). |
| 13 | B | input | Inverting bus input on the ISO35x, which is an input only, not a driver output. |
| 14 | A | input | Noninverting bus input on the ISO35x, which is an input only, not a driver output. |
| 15 | GND2 | power_in | Bus side ground, internally connected to pins 9 and 10. |
| 16 | VCC2 | power_in | Bus side power supply pin for side 2 of the isolator. |
