Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DI1 | input | Transmitter 1 input: when the transmitter is enabled, a low on DI1 forces DO1+ low and DO1- high, and a high forces DO1+ high and DO1- low. |
| 2 | DO1+ | output | Noninverting RS-422 output of transmitter 1. |
| 3 | DO1- | output | Inverting RS-422 output of transmitter 1. |
| 4 | EN | input | Active-HIGH transmitter enable: drive HIGH to enable all transmitters and LOW to three-state (high-impedance) all transmitters; the pin is hot-swap protected. |
| 5 | DO2- | output | Inverting RS-422 output of transmitter 2. |
| 6 | DO2+ | output | Noninverting RS-422 output of transmitter 2. |
| 7 | DI2 | input | Transmitter 2 input: when the transmitter is enabled, a low on DI2 forces DO2+ low and DO2- high, and a high forces DO2+ high and DO2- low. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | DI3 | input | Transmitter 3 input: when the transmitter is enabled, a low on DI3 forces DO3+ low and DO3- high, and a high forces DO3+ high and DO3- low. |
| 10 | DO3+ | output | Noninverting RS-422 output of transmitter 3. |
| 11 | DO3- | output | Inverting RS-422 output of transmitter 3. |
| 12 | EN | input | Active-LOW transmitter enable: drive LOW to enable all transmitters and HIGH to disable (three-state) all transmitters; the pin is hot-swap protected. |
| 13 | DO4- | output | Inverting RS-422 output of transmitter 4. |
| 14 | DO4+ | output | Noninverting RS-422 output of transmitter 4. |
| 15 | DI4 | input | Transmitter 4 input: when the transmitter is enabled, a low on DI4 forces DO4+ low and DO4- high, and a high forces DO4+ high and DO4- low. |
| 16 | VCC | power_in | Positive supply, +3V to +3.6V; bypass VCC to GND with a 0.1µF capacitor. |
