## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NIC | unconnected | No Internal Connection; this pin is not internally connected. |
| 2 | RO | output | Receiver Output Data is high when (A − B) ≥ −30 mV and low when (A − B) ≤ −200 mV, and is tristated when RE is driven high. |
| 3 | RE | input | Receiver Enable Input is active low: driving it low enables the receiver and driving it high disables the receiver. |
| 4 | DE | input | Driver Enable: a high level enables the driver differential outputs Y and Z, and a low level places the driver output into a high impedance state. |
| 5 | DI | input | Transmit Data Input: data to be transmitted by the driver is applied to this input. |
| 6 | GND | power_in | Ground. |
| 7 | GND | power_in | Ground. |
| 8 | NIC | unconnected | No Internal Connection; this pin is not internally connected. |
| 9 | Y | output | Driver Noninverting Output is put into a high impedance state when the driver is disabled or VCC is powered down, to avoid overloading the bus. |
| 10 | Z | output | Driver Inverting Output is put into a high impedance state when the driver is disabled or VCC is powered down, to avoid overloading the bus. |
| 11 | B | input | Inverting Receiver Input. |
| 12 | A | input | Noninverting Receiver Input. |
| 13 | VCC | power_in | 3.0 V to 5.5 V power supply; adding a 0.1 µF decoupling capacitor between the VCC and GND pins is recommended. |
| 14 | VCC | power_in | 3.0 V to 5.5 V power supply; adding a 0.1 µF decoupling capacitor between the VCC and GND pins is recommended. |
