Working Principles

The MAX3467EPA is a transceiver IC designed for half-duplex RS-485/RS-422 communication. It operates by enabling either the driver or receiver circuitry based on the control signals provided. When transmitting data, the driver circuit amplifies the input signal and drives it onto the bus. During reception, the receiver circuit detects and amplifies the incoming signal for further processing.
