MAX14840EASA Integrated Circuit Chip 40Mbps 3.3V Half Duplex RS485 Transceiver, 8-Pin SOIC

The MAX14840EASA is a half duplex RS-485/RS-422 transceiver intended for industrial networks where the bus is exposed to cables, connectors and field wiring, and it protects the interface against the transients that come with that environment.

Data rate is up to 40Mbps, and the driver and receiver meet the RS-485 common mode range so nodes stay interoperable on long buses. ±35kV HBM ESD per JEDEC JS-001-2012 ±20kV air gap and ±12kV contact ESD per IEC 61000-4-2

Large 170mV receiver hysteresis for noise tolerance Symmetrical fail-safe receiver for shorts and opens 3.3V supply, 1.5mA typical, 10uA shutdown

The part is specified over -40°C to +125°C and is supplied in a 8-Pin SOIC package. Every order ships as new stock with full traceability, RoHS compliant and lead free, and samples plus volume pricing are available on request.
