Product details

The MAX14840EASA+: ROHS3 compliant (ROHS3 Compliant per the listing), with no exempt substances — the part ships into EU, UK, and global markets without restriction.

40 Mbps half-duplex transceiver — RS-485/RS-422 on a single 3.3V rail

The MAX14840EASA+ is a 1/1 half-duplex transceiver supporting both RS-422 and RS-485 protocols at a data rate of 40 Mbps. 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.
