Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output: when RE is low and A-B ≥ -50mV, RO is high; when A-B ≤ -200mV, RO is low. |
| 2 | RE | input | Receiver output enable: drive RE low to enable RO, which is high impedance when RE is high; drive RE high and DE low to enter low-power shutdown. |
| 3 | DE | input | Driver output enable: drive DE high to enable the driver outputs, which are high impedance when DE is low; drive RE high and DE low to enter low-power shutdown. |
| 4 | DI | input | Driver input: with DE high, a low on DI forces the noninverting output low and the inverting output high, and a high on DI forces the noninverting output high and the inverting output low. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Noninverting receiver input and noninverting driver output; receiver threshold is -50mV to -200mV with fail-safe to logic high when inputs are open or shorted. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output; receiver threshold is -50mV to -200mV with fail-safe to logic high when inputs are open or shorted. |
| 8 | VCC | power_in | Positive supply; 4.75V ≤ VCC ≤ 5.25V. |
