It delivers 5000 Vrms galvanic isolation between the logic-side and bus-side circuits, which is the rating that decides fit for any application where ground potential differences or safety isolation are required — think motor drives, solar inverters, or medical patient-interface equipment. The 20 Mbps data rate supports high-speed fieldbus links like PROFIBUS or Modbus RTU at extended baud rates, while the unidirectional channel arrangement (2 inputs on side 1, 1 input on side 2) matches the typical half-duplex RS485 topology: one channel for transmit, one for receive, and a third for a control signal like driver enable. Supply voltage is 1.71 V to 5.5 V on the logic side and 4.5 V to 5.5 V on the bus side. ## 5000 Vrms and 35 kV/µs CMTI — the noise-floor gate Isolation voltage is 5000 Vrms. Common-mode transient immunity is 35 kV/µs. Propagation delay is 68 ns max in both directions, which is tight enough for 20 Mbps signaling without bit-rate margin issues on short cable runs. The 15 ns rise/fall time keeps the signal edges clean enough for bus lengths up to a few hundred meters at 20 Mbps, though longer runs may need a slower data rate to manage reflections.","metaTitle":"MAX14941GWE+ RS485 Isolator, 5000Vrms, 20Mbps, 16-SOIC","metaDescription":"MAX14941GWE+ RS485 digital isolator with 5000Vrms isolation, 20Mbps data rate, capacitive coupling.
