ISO1430DWR 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 power supply. |
| 2 | GND1 | power_in | Ground connection for VCC1; pins 2 and 8 must both be connected to GND1. |
| 3 | R | output | Receiver output. |
| 4 | RE | input | Receiver enable; disables receiver output when at high level or open circuit, enables receiver output when at low level. |
| 5 | DE | input | Driver enable; enables driver output when at high level, disables driver output when at low level or open circuit. |
| 6 | D | input | Driver input. |
| 7 | NC | unconnected | No internal connection; connection to power or ground does not affect device function. |
| 8 | GND1 | power_in | Ground connection for VCC1; pins 2 and 8 must both be connected to GND1. |
| 9 | GND2 | power_in | Ground connection for VCC2; pins 9 and 15 must both be connected to GND2. |
| 10 | NC | unconnected | No internal connection; connection to power or ground does not affect device function. |
| 11 | NC | unconnected | No internal connection; connection to power or ground does not affect device function. |
| 12 | A | bidirectional | Bus-side transceiver non-inverted input or output (I/O). |
| 13 | B | bidirectional | Bus-side transceiver inverted input or output (I/O). |
| 14 | NC | unconnected | No internal connection; connection to power or ground does not affect device function. |
| 15 | GND2 | power_in | Ground connection for VCC2; pins 9 and 15 must both be connected to GND2. |
| 16 | VCC2 | power_in | Bus-side power supply. |
