That data rate puts it in the high-speed tier for RS-485 — suitable for applications like motor-drive encoder feedback, fieldbus backplanes, and industrial camera links where the bus must carry fast, differential signalling over twisted-pair cable. The receiver hysteresis of 50 mV provides noise margin on long cable runs where ground-potential differences and reflections degrade signal integrity. ## 8-SOIC footprint — layout and second-source fit Surface-mount assembly with tube packaging — the tube format is typical for prototype and low-volume production runs; for reels, check the ordering options at RFQ. As an active-production part, the MAX14840EASA+ is sourced through authorized distribution channels. No stock-holding claim is made here; the part is quoted to order.","metaTitle":"MAX14840EASA+ RS-485/RS-422 Transceiver, 40 Mbps, 8-SOIC","metaDescription":"MAX14840EASA+ active-production RS-485/RS-422 half-duplex transceiver. 40 Mbps data rate, 3V-3.6V supply, -40°C to +125°C. 8-SOIC package.
