Description

Manufacturer:NVE
Manufacturer Part No:IL3522E

Product Overview

The IL3522E is a RS-422 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. Unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. The IL3522 delivers an exceptional 2.3V differential output into a 54Ω load over the supply range of 4.5 to 5.5V. This provides better data integrity over longer cable lengths, even at data rates as high as 40Mbps. The device is also compatible with 3V supplies, allowing interface to standard microcontrollers without additional level shifting. Current limiting and thermal shutdown features protect against output short circuits and bus contention that may cause excessive power dissipation. Receiver inputs feature a fail-safe if open design, ensuring a logic high R-output if A/B are floating.
