It features +\/-15kV ESD protection on bus pins, fail-safe receiver inputs that guarantee logic-high output when the bus is open or shorted, and reduced slew-rate driver outputs for minimal EMI. The device is ideal for 3.3V logic industrial communication networks.","working_principle":"The MAX3073E converts TTL\/CMOS logic levels to differential RS-485\/RS-422 levels for transmission over twisted-pair cables. The driver outputs use a reduced slew-rate design that limits high-frequency spectral content, reducing EMI and reflections on improperly terminated cables while still supporting 20Mbps data rates. The fail-safe receiver ensures a logic-high output when the bus is open, shorted, or all drivers are tri-stated, preventing false data detection. Current limiting and thermal shutdown protect against fault conditions.","pin_description":"
