What the 5000Vrms isolation and 500kbps data rate mean for your BOM
The 500kbps data rate matches the signaling speed of most RS485 fieldbuses (Modbus RTU, Profibus DP at lower baud rates), so it slots into existing twisted-pair networks without needing a faster — and more expensive — isolator. The part uses magnetic coupling technology rather than capacitive coupling, which typically gives better common-mode transient immunity — here rated at 100kV/µs typical. That matters when the isolator sits on a motor-drive board where switching IGBTs slam the bus with fast voltage edges. The 610ns maximum propagation delay and 40ns pulse-width distortion are adequate for half-duplex RS485 polling cycles; a faster isolator would add cost without throughput gain at 500kbps.
Temperature range and supply — where this part lives on the board
No isolated power output on this device; the bus-side supply must be provided externally. The 20-SOIC wide-body package (0.295-inch width, 7.50mm) provides the creepage distance needed to maintain the 5000Vrms isolation rating across the PCB. Surface-mount assembly is standard.
