Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output: when RE is low, RO is high if (A-B) ≥ -50mV and low if (A-B) ≤ -200mV; high-impedance when RE is high. |
| 2 | ~{RE} | input | Receiver output enable, active low: RO is active when RE is low and high-impedance when RE is high; RE high with DE low enters low-power shutdown, and RE has a hot-swap input structure. |
| 3 | DE | input | Driver output enable: driver outputs are active when DE is high and high-impedance when DE is low; DE low with RE high enters low-power shutdown, and DE has a hot-swap input structure. |
| 4 | DI | input | Driver input: with DE high, a low on DI forces A low and B high, and a high on DI forces A high and B low. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output (half-duplex bus pin, ±16kV IEC 61000-4-2 ESD protected). |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output (half-duplex bus pin, ±16kV IEC 61000-4-2 ESD protected). |
| 8 | VCC | power_in | Positive supply, 4.5V ≤ VCC ≤ 5.5V, bypassed to ground with a 0.1µF capacitor. |
