Working Principles

The SN65HVD1477D is a transceiver IC designed for half-duplex communication in industrial applications. It operates by converting digital signals into differential voltage levels suitable for transmission over a communication line. The driver and receiver sections of the IC are controlled by the DE (Driver Enable) and RE (Receiver Enable) pins, respectively. The RS (Slope Control) pin allows adjustment of the bus line's signal rise and fall times.
