The MAX491CSD+T: It pushes data at 2.5 Mbps over a single twisted pair, with 70 mV of receiver hysteresis to reject noise on long cable runs — useful for industrial bus lines where signal integrity matters more than raw speed.
The MAX491CSD+T is a full-duplex transceiver. It handles RS-485 and RS-422 protocols with one driver and one receiver on-chip.
The part is ROHS3 compliant. No UL, REACH, or IEC documentation is listed in the available records.
