It integrates a single driver and a single receiver (1/1) in one 14-SOIC package, making it a compact solution for balanced differential-data links in industrial and instrumentation systems. ## Supply voltage and temperature range — industrial-grade fit The -40°C to 125°C operating range covers the extended industrial temperature band, so it can be placed in a motor-drive cabinet or an outdoor telecom enclosure without derating. Receiver hysteresis of 10 mV provides noise immunity on long cable runs, reducing bit errors in electrically noisy environments. ## Package, compliance and sourcing posture Analog Devices lists the MAX3491AEASD+T as ROHS3 compliant, so it meets the current restriction-of-hazardous-substances directive without exemption.","metaTitle":"MAX3491AEASD+T Analog Devices RS422/RS485 Transceiver","metaDescription":"MAX3491AEASD+T Analog Devices RS422/RS485 full-duplex transceiver, 20Mbps data rate, 3V-3.6V supply, -40°C to 125°C, 14-SOIC.
