Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDDA | power_in | Logic-side (A) power supply. Operating range 2.375-5.5 V (recommended 2.5-5.5 V). |+| 2 | GNDA | power_in | Logic-side (A) ground reference. |+| 3 | RO | output | Receiver output. RO is high when A is at least 200 mV above B; RO is low when A is at least 200 mV below B. |+| 4 | /RE | input | Receiver enable, active low. RE low enables the receiver; RE high places the receiver output in high impedance. |+| 5 | DE | input | Driver enable, active high. DE high enables the driver; DE low places driver outputs in high impedance. With DE high the device is in transmit mode; with DE low and /RE low it is in receive mode. |+| 6 | DI | input | Driver data input. DI high drives A high and B low; DI low drives the opposite. |+| 7 | GNDA | power_in | Logic-side (A) ground reference. |+| 8 | GNDA | power_in | Logic-side (A) ground reference. |+| 9 | GNDB | power_in | Bus-side (B) ground reference. |+| 10 | GNDB | power_in | Bus-side (B) ground reference. |+| 11 | Y | output | Bus-side non-inverting driver output (RS-485 differential transmit +). |+| 12 | Z | output | Bus-side inverting driver output (RS-485 differential transmit -). |+| 13 | B | input | Bus-side inverting receiver input (RS-485 differential receive -). |+| 14 | A | input | Bus-side non-inverting receiver input (RS-485 differential receive +). |+| 15 | GNDB | power_in | Bus-side (B) ground reference. |+| 16 | VDDB | power_in | Bus-side (B) power supply.
