Pinout

The SN65HVD82DR is an integrated circuit designed for RS-485 and RS-422 communication. It is a differential line transceiver with a pin count of 8. Here is a brief description of its pins and functions:
1. Pin 1 - RO (Receiver Output): Provides the output of the receiver. This pin outputs the received data to the microcontroller or other logic circuits.

2. Pin 2 - RE (Receiver Enable): Controls the receiver. A low level enables the receiver, and a high level disables it.
3. Pin 3 - DE (Driver Enable): Controls the driver. A high level enables the driver, and a low level disables it.
4. Pin 4 - DI (Driver Input): Accepts data from a microcontroller or logic circuitry to be transmitted over the bus.
5. Pin 5 - GND (Ground): Ground reference for the device.
6. Pin 6 - A (Non-Inverting Driver Output / Receiver Input): Connected to the bus for differential data transmission and receiving.
7. Pin 7 - B (Inverting Driver Output / Receiver Input): Connected to the bus for complementary differential data.
8. Pin 8 - VCC (Supply Voltage): Powers the device, typically with a voltage range of 3.3V to 5V.
These pins facilitate bidirectional data transmission over long distances, making the SN65HVD82DR suitable for industrial communication applications.
