Working Principles

The SN65HVD379D is a transceiver IC designed for half-duplex communication. It utilizes differential signaling to transmit and receive data between microcontrollers and other devices in industrial applications. The driver section converts the digital signals from the microcontroller into differential voltage levels suitable for transmission over long distances. The receiver section receives the differential signals, amplifies them, and converts them back into digital signals for the microcontroller to process.
