Fun Facts
A lot of nerve...
 
Nerve Cell
IsoLoop Isolators are more than 10,000 times faster than electrical synapses, the fastest known links between nerve cells (10 ns typical propagation delay for IL700-Series Isolators compared to 200 µs synaptic delay for an electrical synapse).

Narrow-Body SOIC-16 Isolators
 
Think Thin!
The world’s densest isolators, IsoLoop “Dash Three” Isolators provide a full line of unique 0.15", narrow-body SOIC-16 isolators—half the size of other isolators.

Thin SOIC Package
Like all IsoLoop Isolators, these products feature minimal signal distortion, wide temperature range, low power consumption, and unlimited life. Narrow-body isolators are available in a variety of input, output, and channel configurations, as well as a full line of isolated RS-485/RS-422/PROFIBUS transceivers.

Key narrow-body isolator features include:
  • 0.15", 16-pin SOIC
  • Passive or digital inputs
  • Three, four, or five channels or isolated RS-422/RS-485
  • IEC 61010-2001 approved
  • 125°C (IL700T-Series)

Nearly 20 Dash Three part types are in stock and available for immediate delivery with no minimum order:

Application Corner
Power Supplies Declare Independence
 
Power supplies need their independence, and IsoLoop Isolators can isolate and level-shift between components on different supplies.

The figure below shows a common application using an IL717 to isolate and level-shift data from a 5-volt powered sensor and ADC to a 3.3 V logic controller:

Isolated Sensor / ADC Application
Isolating Independent Power Supplies

Isolation keeps the two power supplies independent with separate digital and analog ground current paths. This eliminates ground loops, minimizes noise, and improves measurement accuracy.

IL700/IL200-Series Isolators are available in a variety of configurations with up five channels per device. Versions are available in NVE’s unique, ultra-dense 0.15" narrow-body SOIC package (see featured products above).

So use isolation and declare your independence.
