The MAX3032ECSE+ is a dedicated RS-422/RS-485 line driver with four independent outputs and zero receivers on-chip. That 4/0 driver/receiver count means this part handles the transmit side only — you pair it with a separate RS-485 receiver or transceiver on the same bus if bidirectional communication is needed. Rated for 20Mbps over twisted-pair cabling, the driver meets the RS-422 and RS-485 electrical standards for differential signaling. At that data rate, the output slew rate is fast enough for high-speed industrial backplanes or point-to-point links, but the short rise time also means the PCB layout needs controlled impedance and proper termination to avoid reflections.
3.3V single-rail supply, commercial temp grade
Supply range is 3V to 3.6V, so a nominal 3.3V rail is the target. No dual supply or 5V rail needed — this simplifies the power tree if the rest of the logic is also 3.3V. That covers indoor equipment, test gear, and office-environment control panels but not outdoor or under-hood automotive use. For extended temperature ranges, the MAX3032EESE+ (industrial -40°C to +85°C) is the sibling to look at. The supplier device package is also 16-SOIC, so no confusion between narrow and wide SOIC variants.
Active production, ROHS3 compliant
ROHS3 compliant, meaning it meets the latest EU RoHS exemption limits including the four phthalates. No special handling or exemption paperwork needed for EU-market shipments.
