Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection; the pin is not connected internally. |
| 2 | RO | tri_state | Receiver output: high if A > B by at least 0.2V, low if A < B by 0.2V or more, high if A and B are floating; high-impedance when RE is high. |
| 3 | RE | input | Receiver output enable: RO is enabled when RE is low and is high-impedance when RE is high. |
| 4 | DE | input | Driver output enable: outputs Y and Z are enabled when DE is high and are high-impedance when DE is low. |
| 5 | DI | input | Driver input: a low on DI forces Y low and Z high, and a high on DI forces Y high and Z low. |
| 6 | GND | power_in | Ground connection. |
| 7 | GND | power_in | Ground connection. |
| 8 | NC | unconnected | No connection; the pin is not connected internally. |
| 9 | Y | tri_state | Noninverting driver output, ±15kV HBM ESD protected on the RS-485 bus. |
| 10 | Z | tri_state | Inverting driver output, ±15kV HBM ESD protected on the RS-485 bus. |
| 11 | B | input | Inverting receiver input, ±15kV HBM ESD protected; 1/8 unit load with -7V to +12V common-mode range. |
| 12 | A | input | Noninverting receiver input, ±15kV HBM ESD protected; 1/8 unit load with -7V to +12V common-mode range. |
| 13 | NC | unconnected | No connection; the pin is not connected internally. |
| 14 | VCC | power_in | System power supply input, 4.5V to 5.5V. |
