Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | R | output | Receiver output, driven high when A-B is above VIT+ or inputs are open/shorted/terminated (full fail-safe), high-Z when /RE is high; VOL 0.4 V max at IOL = 8 mA. |
| 2 | RE | input | Receiver enable, active low (/RE); logic low enables the receiver and high puts R in high-impedance, with VIH 2 V min and VIL 0.8 V max. |
| 3 | DE | input | Driver enable, active high; high enables the driver outputs A/B and low (or open) disables them to high-Z, with VIH 2 V min and VIL 0.8 V max. |
| 4 | D | input | Driver input; with the driver enabled, high drives A high and B low, and low drives A low and B high, with VIH 2 V min and VIL 0.8 V max. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | A | bidirectional | Non-inverting RS-485 bus pin (driver output / receiver input), range -9 V to +14 V absolute max, ±12 kV HBM ESD. |
| 7 | B | bidirectional | Inverting RS-485 bus pin (driver output / receiver input), range -9 V to +14 V absolute max, ±12 kV HBM ESD. |
| 8 | VCC | power_in | Supply voltage input, 3 V to 5.5 V recommended operating range, -0.3 V to +7 V absolute maximum. |
