ISO1410DWR from Texas Instruments, 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 | VCC1 | power_in | Logic-side supply. Operating range 1.71 V to 5.5 V. Local bypass capacitor to GND1 required. |
| 2 | GND1 | power_in | Logic-side ground reference for VCC1. Pins 2 and 8 must both be tied to GND1. |
| 3 | R | output | Receiver output. Drives logic-level data recovered from the isolated RS-485 bus (A/B) to the MCU. |
| 4 | RE | input | Receiver enable, active-low. Receiver output is enabled when RE is low; disabled (high-Z on R) when RE is high or left open. |
| 5 | DE | input | Driver enable, active-high. Driver outputs on the bus (A/B) are enabled when DE is high; disabled when DE is low or open. |
| 6 | D | input | Driver input. Logic-side data to be transmitted onto the isolated RS-485 bus when DE is asserted. |
| 7 | NC | unconnected | No internal connection. May be tied to any supply or ground on the PCB without affecting device operation. |
| 8 | GND1 | power_in | Logic-side ground reference for VCC1. Both pin 2 and pin 8 must be connected to GND1. |
| 9 | GND2 | power_in | Bus-side ground reference for VCC2. Both pin 9 and pin 15 must be connected to GND2. |
| 10 | NC | unconnected | No internal connection. May be left floating or tied to PCB supply/ground without affecting operation. |
| 11 | NC | unconnected | No internal connection on the half-duplex ISO1410 variant. (This position is used for the Y driver output on the full-duplex ISO1412.) |
| 12 | A | bidirectional | Non-inverting RS-485 bus I/O. Acts as driver output when DE=1 and as receiver non-inverting input when RE=0. Absolute-max bus voltage ±18 V relative to GND2; ±16 kV IEC 61000-4-2 contact ESD rated. |
| 13 | B | bidirectional | Inverting RS-485 bus I/O. Acts as driver complementary output when DE=1 and as receiver inverting input when RE=0. Absolute-max bus voltage ±18 V relative to GND2; ±16 kV IEC 61000-4-2 contact ESD rated. |
| 14 | NC | unconnected | No internal connection on the half-duplex ISO1410 variant. (This position is used for the A input on the full-duplex ISO1412.) |
| 15 | GND2 | power_in | Bus-side ground reference for VCC2. Both pin 9 and pin 15 must be connected to GND2. |
| 16 | VCC2 | power_in | Bus-side (isolated) supply for the RS-485 transceiver. Operating range 3 V to 5.5 V. Local bypass capacitor to GND2 required. |
