10 Mbps RS-485/RS-422 transceiver — full-duplex, single 5 V supply
The MAX3089EESD+ is a full-duplex RS-485/RS-422 transceiver from Analog Devices, integrating one driver and one receiver in a single 14-SOIC package.
Receiver hysteresis and noise margin
The receiver includes 100 mV of hysteresis, which provides noise immunity on long cable runs where ground-potential differences and reflections can corrupt the differential signal. This is a datasheet-specified minimum — the actual margin is wider than the bare 100 mV figure suggests, since the hysteresis is built into the comparator stage and does not require external resistors.
Active production and compliance
Sourced through independent distribution channels against an RFQ.
