QSOP RS-485 Transceiver |
|
|
 The
world’s fastest isolated RS-485 transceivers are now also the world’s
smallest. The new IL3685-1E is an ultrahigh-speed isolated transceiver in NVE’s
ultraminiature, low thermal resistance QSOP-16 package.
Features include:
• 40 Mbps data rate
• PROFIBUS compliant
• 600 VRMS working voltage
• 2500 VRMS isolation voltage
• 44000 year barrier life
• Low EMC footprint
• Thermal shutdown protection
• 4 mm by 5 mm low thermal resistance QSOP

 |
0.3" SOIC-16,
0.15" SOIC-16, and
QSOP-16 packages. |
Like all IsoLoop®
isolators, the new device uses NVE’s patented IsoLoop spintronic Giant Magnetoresistance
(GMR) technology. A unique ceramic/polymer composite barrier provides excellent isolation and virtually
unlimited barrier life.
There are now ten members
of NVE’s isolated digital transceiver family in various packages, including
the unique QSOPs, the industry’s smallest isolated transceivers:

World’s
Fastest Isolated RS-485 Transceiver Demonstration
To prove they really are the world’s fastest isolated RS-485 transceivers,
NVE’s Chris Olson connected two 40 Mbps evaluation boards with 10 meters
of twisted-pair shielded cable:
Demonstrating the world's fastest isolated RS-485 transceivers.
When the lab results were in, propagation delay measured just 96 ns for two
transceivers, and about 33 ns of that was the speed of light through the
10 meter cable. That’s much faster than any competitive parts. Typical
pulse skew is only one nanosecond, and the transceivers are also very well-matched—skew
between any two devices is only 4 ns.
