For BOM planning, treat it as a current-production part with no imminent obsolescence risk. ## Receiver hysteresis — noise margin on the bus The receiver includes 25 mV of hysteresis, which helps reject noise on long cable runs. For a 250 kbps link in an electrically noisy factory environment, that hysteresis reduces the chance of bit errors from coupled interference.","metaTitle":"MAX3430ESA+ RS-485/RS-422 Transceiver, Half-Duplex, 250 kbps","metaDescription":"MAX3430ESA+ is an industrial RS-485/RS-422 transceiver in an 8-SOIC package.

The supply range of 3V to 3.6V means the part operates from a 3.3V rail and is directly compatible with 3.3V RS-485 buses. It is not 5V-tolerant on the supply or logic inputs."},{"question":"Is MAX3430ESA+ half-duplex or full-duplex?","answer":"It is half-duplex.
