Data rate is 10 Mbps — fast enough for a multi-drop sensor network polling at sub-millisecond intervals, but the cable length must be derated from the standard 1200 m at 100 kbps down to roughly 100 m at this speed to keep reflections below the 25 mV receiver hysteresis threshold. ## Supply rail and temperature envelope If your backplane bus is 3.3 V, this part needs a local 5 V regulator; the 25 mV hysteresis gives clean noise rejection on a 5 V bus with common-mode shifts up to -7 V to +12 V per RS485. ## Active production and compliance The 8-SOIC footprint (3.90 mm width) is a standard JEDEC outline; the tube packaging means it ships in quantities that suit prototype builds and low-volume production runs equally.","metaTitle":"MAX3443EASA+ RS485 Transceiver, 10Mbps, 8-SOIC","metaDescription":"Analog Devices MAX3443EASA+ RS485/RS422 half-duplex transceiver, 10Mbps data rate, 4.75-5.25V supply, -40 to +125°C.
