Active RS422/RS485 transceiver — 20 Mbps full-duplex in 14-SOIC
The MAX3491AEASD+T is an active-production Analog Devices transceiver supporting full-duplex RS422 and RS485 communication at a data rate of 20 Mbps. 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.
