NVE Introduces Low-Cost Isolated RS-485 Transceivers

NVE IL3085-3E IL3085E

NVE Corporation has introduced low-cost versions of its award-winning IsoLoop® isolated RS-485 transceivers.

World’s Smallest

NVE’s unique narrow-body versions, designated with the -3E suffix, are the world’s smallest isolated transceivers. The 0.15-inch wide 16-pin “dash 3” SOIC package is half the size of other isolators.

NVE - IL3085-3E, IL3085E

Best-in-Class Specifications

The new transceivers feature best-in-class speed and efficiency for a low-cost transceiver, including 4 Mbps data rate and 3 milliamp typical controller-side quiescent current.

The parts meet or exceed ANSI RS-485 and ISO 8482:1987(E) industry standards.

Rugged and Reliable

Designed for rugged industrial applications, IL3085 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.
