With extended common-mode range and low bus leakage, it is designed for robust half-duplex communication in industrial and building automation networks.","working_principle":"The device converts single-ended TTL\/CMOS logic to differential RS-485 bus signals. The driver outputs differential voltage on A\/B pins, while the receiver detects differential voltages as small as \u00b1200mV. Direction control (DE\/RE) switches between transmit and receive modes.","pin_description":"
