Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output: with RE low, RO is high when A−B is at or above −50 mV and low when A−B is at or below −200 mV, and it is high-impedance when RE is high. |
| 2 | RE | input | Active-low receiver output enable: RO is active when this pin is low and high-impedance when it is high, and RE high together with DE low puts the device into low-power shutdown (hot-plug input). |
| 3 | DE | input | Driver output enable: outputs A and B are active when DE is high and high-impedance when DE is low, and DE high is not a shutdown condition while DE low with RE high enters low-power shutdown (hot-plug input). |
| 4 | DI | input | Driver input: with DE high, a low on DI drives A low and B high, and a high on DI drives A high and B low. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | A | bidirectional | Non-inverting receiver input and driver output on the bus; the absolute maximum voltage range for A and B is −7 V to +12 V, with ±16 kV IEC 61000-4-2 ESD protection. |
| 7 | B | bidirectional | Inverting receiver input and driver output on the bus; the absolute maximum voltage range for A and B is −7 V to +12 V, with ±16 kV IEC 61000-4-2 ESD protection. |
| 8 | VCC | power_in | Positive supply: 3.15 V ≤ VCC ≤ 3.45 V; place a 0.1 µF capacitor to ground. |
