| Supply voltage | - | The whole point of the family: no separate isolated supply winding needed on the bus side - and the decoupling that comes with it (VISOOUT/VISOIN with their 0.1uF and 0.01uF capacitors) is part of the design. |
| Memory & Peripherals | - | Where the 16-pin parts isolate data only, these isolate data AND power - the reason new designs stopped laying out the extra winding. |
| Case | SOIC-16 wide body (16-lead SOIC_W) | SOIC-20 wide body |
| Compatibility Level | - | Functional Equivalent |
| Component Category | Isolated RS-485 Transceivers | - |
| Core & Architecture | - | The next generation folds the isolated DC-DC converter into the package (isoPower): the bus side powers itself from the logic side across the barrier - 16Mbps (2582E) or 500kbps (2587E) with the isolated rail included. |
| Firmware Notes | - | A 20-pin part is not a repair substitution for a 16-pin socket: the honest use is redesign and new boards, where the BOM shrinks by the whole isolated supply. For repairs, stay in the 16-pin row. |
| Hardware Notes | - | 20-lead wide SOIC with its own decoupling network. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Market Reality | The ADM2483 is the isolated half-duplex RS-485 transceiver of industrial Modbus loops, servo drives and PLC networks: a 2.5kV rms iCoupler barrier with true fail-safe receivers, a slew-limited driver, more than 25kV per microsecond of common-mode transient immunity, and a 16-pin wide SOIC that its 20 megabit PROFIBUS twin, the ADM2486, shares pin for pin. The substitution conversation around it has two halves: inside the 16-pin row it is a clean speed ladder, and outside it the trap is architectural - the 2483 isolates the DATA, and the bus-side supply must be isolated by the board. A repair that ties GND2 to logic ground has built a very robust non-isolated transceiver out of an expensive isolated one. | - |
