Data rate is 250kbps, suited for industrial fieldbus links and building-automation networks where the bus runs at moderate speed over twisted-pair cable. Supply range is 3V to 3.6V, so it operates from a 3.3V rail with margin. Receiver hysteresis of 25 mV filters noise on the bus — the differential input threshold is centred at zero with a 50 mV dead band, which prevents chatter on idle or lightly loaded lines. The supplier device package is 8-SOIC, so the PCB land pattern matches the industry-standard narrow-body SOIC-8 with 1.27 mm pitch. Not rated for extended industrial or automotive temperature extremes.","metaTitle":"MAX3430CSA+T RS-485/RS-422 Transceiver, Half-Duplex, 250kbps","metaDescription":"MAX3430CSA+T from Analog Devices — RS-485/RS-422 half-duplex transceiver, 250kbps data rate, 3V-3.6V supply, 8-SOIC.
