NVE Introduces Narrow-Body Isolated RS-485 And PROFIBUS Transceivers

B

est-in-Class Specifications



Both new transceivers feature best-in-class speed and efficiency specifications, including 40 Mbps data rate, 20 nanosecond typical propagation delay, and 3 milliamp typical controller-side quiescent current.



Both meet or exceed ANSI RS-485 and ISO 8482:1987(E) industry standards. IL3685-3E transceivers are also fully PROFIBUS compliant, including the rigorous PROFIBUS differential output voltage specifications.



Rugged and Reliable



Designed for rugged industrial applications, NVE’s IL35- and IL36-Series isolated transceivers have a -40 to +85 degree Celsius temperature range, 15 kV bus ESD protection, and current limiting and thermal shutdown features. Receiver inputs feature a “fail-safe if open” design.



Parts are IEC 61010-2001 approved and UL 1577 recognized. Unlike optocouplers or other isolation technologies, IsoLoop isolators have indefinite life at high voltage.



Available Now



The IL3585-3E and IL3685-3E are both in stock for immediate delivery. Pricing for the new parts is $3.40 each for 1,000 pieces, slightly less than the corresponding wide-body parts.



Evaluation Boards



Evaluation boards are also available for both new parts. Both boards provide complete nodes with reference design practices.



The RS-485 evaluation board includes an RJ45 bus connector, and the PROFIBUS board includes a PROFIBUS-standard DB9 connector.



The suggested retail price of the evaluation boards is $74.95.
