ADM2687EBRIZ-RL7 from Analog Devices, in a SOIC-16-300mil. 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 | GND1 | power_in | Logic-side ground reference. |
| 2 | VCC | power_in | 5 V or 3.3 V logic-side power supply input. |
| 3 | RxD | tri_state | Receiver data output, high when (A−B)≥−30 mV, low when (A−B)≤−200 mV, tri-state when disabled (RE high). |
| 4 | RE | input | Receiver enable input, active low; enables receiver when low, disables when high. |
| 5 | DE | input | Driver enable input, active high; enables driver when high, disables when low. |
| 6 | TxD | input | Driver data input for transmission through RS-485 bus. |
| 7 | VCC | power_in | 5 V or 3.3 V logic-side power supply input. |
| 8 | GND1 | power_in | Logic-side ground reference. |
| 9 | GND2 | power_in | Bus-side ground reference. |
| 10 | VISOOUT | power_out | 3.3 V isolated power output; must be connected externally to VISOIN pin 15. |
| 11 | Y | tri_state | Driver non-inverting differential output, tri-state when DE low. |
| 12 | Z | tri_state | Driver inverting differential output, tri-state when DE low. |
| 13 | B | input | Receiver inverting differential input, −7 V to +12 V common mode range. |
| 14 | A | input | Receiver non-inverting differential input, −7 V to +12 V common mode range. |
| 15 | VISOIN | power_in | Isolated power input; must be connected externally to VISOOUT pin 10. |
| 16 | GND2 | power_in | Bus-side ground reference. |
