Propagation delay is a symmetrical 60 ns max in both directions, so half-duplex turnaround doesn't accumulate skew that eats into the bit timing budget at 16 Mbps. ## Supply rails and temperature range — bridging legacy and modern logic Rated for both 3V and 5V supplies, the ADM2490EBRWZ can sit on a 3.3V microcontroller UART and still drive a 5V RS-485 bus without external level translation — one less component on the BOM. The 25 kV/µs common-mode transient immunity means the receiver won't glitch when a motor drive or VFD couples fast transients across the isolation barrier. ## Package and footprint — 16-SOIC wide-body Housed in a 16-SOIC wide-body (7.50 mm width) package, surface-mount only. The wide-body SOIC gives better creepage distance for the 5000 Vrms rating compared to a narrow SOIC — layout engineers should maintain the recommended clearance under the part on the PCB. No isolated power output on this variant; the bus-side VCC comes from an external supply.","metaTitle":"ADM2490EBRWZ iCoupler RS-422/RS-485 Isolator, 16 Mbps","metaDescription":"ADI ADM2490EBRWZ isolated RS-422/RS-485 transceiver, 16 Mbps data rate, 5000 Vrms isolation, -40°C to 105°C, 16-SOIC.
