This hysteresis band prevents output chatter when the differential input signal is near the threshold, a common issue in electrically noisy industrial environments. The 10 Mbps data rate supports high-speed point-to-point or multi-drop links, with the full-duplex architecture allowing simultaneous transmit and receive over a single twisted-pair or two-pair cable. ## Active lifecycle and RoHS3 compliance No PCN or LTB date has been issued for this part. The part ships in tape and reel (TR) packaging, with cut tape (CT) also available — the typical ordering format for volume production or prototype quantities. ## Temperature grade and deployment context Rated for the commercial temperature range of 0°C to 70°C, this transceiver suits indoor equipment, data acquisition systems, and industrial control panels where ambient temperature stays within that band. For extended-temperature or outdoor deployments, the industrial-grade MAX3491E variant (not covered here) is the typical alternative.","metaTitle":"MAX3491ECSD+T RS-485/RS-422 Transceiver, 10 Mbps, 14-SOIC","metaDescription":"MAX3491ECSD+T Analog Devices RS-485/RS-422 transceiver, full duplex, 10 Mbps data rate, 3V-3.6V supply, 14-SOIC.
