Pinout

The ADM485EARZ is a low-power, half-duplex RS-485/RS-422 transceiver. It comes in a standard 8-pin SOIC (Surface Mount) package. The pinout and functions are as follows:
1. RO (Receive Output): Outputs the received signal from the bus.
2. RE (Receive Enable): Active low input that enables the receiver.
3. DE (Driver Enable): Active high input that enables the driver.
4. DI (Driver Input): Input for the data to be transmitted.
5. A (Non-inverting Output): Differential output for the positive signal.
6. B (Inverting Output): Differential output for the negative signal.
7. GND: Ground reference for the device.
8. VCC: Power supply pin, typically connected to +5V.
The device operates with low power consumption and is suitable for long-distance data transmission in noisy environments.
