Rated for 10 Mbps data rate, it handles the upper end of RS485 signaling — suitable for multi-drop industrial buses, building automation backbones, and instrumentation links where the bus clock runs above the typical 115.2 kbps or 1 Mbps. Housed in a 14-SOIC (0.154\", 3.90mm width) package — the narrow-body SOIC-14 footprint matches industry-standard land patterns for this pin count. Surface-mount assembly; the tape-and-reel option (TR) suits automated pick-and-place, while the cut-tape (CT) variant is available for prototype or low-volume builds. The 50 mV receiver hysteresis provides noise margin on long bus runs — the differential input won't chatter on a slowly rising signal at the far end of a 4000-foot RS485 cable. ROHS3 compliant, meeting the current EU restriction-hazardous-substances directive for lead-free assembly. Rated for commercial temperature range (0°C to 70°C), so it is specified for indoor equipment, telecom racks, and controlled-environment industrial enclosures — not for extended outdoor or under-hood automotive use.","metaTitle":"MAX3491CSD+T RS485/RS422 Transceiver, 10Mbps, 14-SOIC","metaDescription":"MAX3491CSD+T RS485/RS422 full-duplex transceiver, 10Mbps data rate, 3-3.6V supply, 14-SOIC.
