Working Principles

The MAX3469ESA+TG002 is a low-power transceiver designed for half-duplex communication on RS-485/RS-422 buses. It provides a robust interface between microcontrollers and industrial networks, ensuring reliable data transmission in noisy environments. The transceiver operates by enabling either the driver or receiver mode using the DE/RE pin. When transmitting data, the driver inputs the signal through the DI pin, which is then transmitted differentially through the A and B pins. On the receiving end, the transceiver outputs the received data through the Y and Z pins.
