Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCCA | power_in | Supply voltage for side A; recommended operating range 4.5V to 5.5V. |
| 2 | DIR | input | Direction control input; low selects B to A data translation, high selects A to B data translation. |
| 3 | A1 | bidirectional | Transceiver I/O pin for 5V side A bus; bidirectional data path. |
| 4 | A2 | bidirectional | Transceiver I/O pin for 5V side A bus; bidirectional data path. |
| 5 | A3 | bidirectional | Transceiver I/O pin for 5V side A bus; bidirectional data path. |
| 6 | A4 | bidirectional | Transceiver I/O pin for 5V side A bus; bidirectional data path. |
| 7 | A5 | bidirectional | Transceiver I/O pin for 5V side A bus; bidirectional data path. |
| 8 | A6 | bidirectional | Transceiver I/O pin for 5V side A bus; bidirectional data path. |
| 9 | A7 | bidirectional | Transceiver I/O pin for 5V side A bus; bidirectional data path. |
| 10 | A8 | bidirectional | Transceiver I/O pin for 5V side A bus; bidirectional data path. |
| 11 | GND | power_in | Ground reference for signal and power return. |
| 12 | GND | power_in | Ground reference for signal and power return. |
| 13 | GND | power_in | Ground reference for signal and power return. |
| 14 | B8 | bidirectional | Transceiver I/O pin for 3.3V side B bus; bidirectional data path. |
| 15 | B7 | bidirectional | Transceiver I/O pin for 3.3V side B bus; bidirectional data path. |
| 16 | B6 | bidirectional | Transceiver I/O pin for 3.3V side B bus; bidirectional data path. |
| 17 | B5 | bidirectional | Transceiver I/O pin for 3.3V side B bus; bidirectional data path. |
| 18 | B4 | bidirectional | Transceiver I/O pin for 3.3V side B bus; bidirectional data path. |
| 19 | B3 | bidirectional | Transceiver I/O pin for 3.3V side B bus; bidirectional data path. |
| 20 | B2 | bidirectional | Transceiver I/O pin for 3.3V side B bus; bidirectional data path. |
| 21 | B1 | bidirectional | Transceiver I/O pin for 3.3V side B bus; bidirectional data path. |
