Isolated RS485/RS422 Interface

The IL3522 is a galvanically isolated, high-speed differential bus transceiver, designed for bidirectional data Communication on balanced transmission lines. The device uses NVEs patented* IsoLoop spintronic Giant Magnetoresistance (GMR) technology. The IL3585 delivers an exceptional 2.3 V differential output into a 54 load over the supply range of 4.5 V to 5.5 V. This provides better data integrity over longer cable lengths, even at data rates as high as 40 Mbps. The device is also compatible with 3.3 V input supplies, allowing Interface to standard Microcontrollers without additional level shifting. By NVE Corp.
