PUNXSU-TAWNEY, Penn.— Feb. 2, 2013— It will be an early spring, according to Punxsutawney Phil.
“I left the isolation of my ground loop, and my current sense, my gauss, is an early spring.” |

 Narrow-Body Isolated
RS-485 and PROFIBUS Transceivers |
|
|
NVE recently introduced narrow-body versions of the popular IL3585 high-speed RS-485 transceivers and IL3685 PROFIBUS-compliant transceivers.
World’s Smallest
The narrow-body versions, designated with the -3E suffix, are the
world’s smallest isolated transceivers. The “dash 3” 0.15-inch wide,
1.8 mm clearance height 16-pin SOIC packages are half the size of other isolators.
Best-in-Class Specs
Both new transceivers feature best-in-class speed and efficiency specifications, including 40 Mbps data rate,
20 ns typical propagation delay, and 3 mA 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 UL 1577 recognized and IEC 61010-1 approved. Unlike optocouplers or other isolation technologies, IsoLoop isolators have indefinite barrier life.
Available Now
The IL3585-3E and IL3685-3E are both in stock for immediate delivery.

RS-485 and PROFIBUS
Narrow-Body Isolator Eval Boards |
|
|
Evaluation boards are available for both new narrow-body transceivers, the IL3585-3 and IL3685-3. 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.
PROFIBUS Evaluation Board
The evaluation boards demonstrate the space savings of NVE’s unique “dash 3” 0.15-inch wide,
1.8 mm clearance height packages. Other features include:
• 40 Mbps data rate
• 20 ns typical propagation delay
• 3 mA typical controller-side quiescent current
• 15 kV bus ESD protection
