It handles data rates up to 16 Mbps, making it a fit for high-speed industrial networks, motor drives, and building automation where the bus needs to keep up with fast sensor polling or control loops. The 100 mV receiver hysteresis provides noise margin on long cable runs, and the -40°C to 125°C operating range covers outdoor cabinets and engine-bay environments without derating. ## 3.3 V supply — not a 5 V part Supply range is 3 V to 3.6 V, so this transceiver runs from a 3.3 V rail. If your existing bus transceivers are 5 V, this part won't plug in without a level translator or a separate supply. The narrow window means the rail needs to stay clean — a switching regulator with 100 mV ripple eats into the margin. For new 3.3 V-only designs, the MAX3078EASA+ avoids the extra regulator a 5 V transceiver would need. ## Active production, ROHS3, tube packaging Lifecycle status is Active per the manufacturer, with no NRND or EOL flags. ROHS3 compliant, so it passes the usual environmental compliance checks for EU and North American markets. For reel quantities, check the alternate ordering code (MAX3078EASA+T). ## Where it fits on the board Package is 8-SOIC (3.90 mm width), a common footprint that matches many RS-485 transceivers. Single driver and single receiver — one bus channel. The half-duplex architecture means the driver and receiver share the same bus pair; the MCU controls direction via the DE and RE pins. No exposed pad, so thermal dissipation is through the leads — fine for the typical 16 Mbps signaling load, but if you're driving a heavily loaded bus at high speed, keep the ambient airflow in mind.","metaTitle":"MAX3078EASA+ RS-485/RS-422 Transceiver, 16 Mbps, 8-SOIC","metaDescription":"MAX3078EASA+ half-duplex RS-485/RS-422 transceiver from Analog Devices. 16 Mbps data rate, 3V–3.6V supply, -40°C to 125°C range.
