 Isolating
a One-Wire Serial Bus
Doesn’t Have to Be Scary
You know you should isolate your one-wire serial bus for safety and noise immunity,
but you're afraid it's going to be too complicated?
With their small size, high input impedance, and output enable pins, IL700-Series
Isolators are ideal for isolating one-wire bidirectional serial busses.
These busses are common for sensors and controls. Isolation can reduce noise and
increase transmission distance.
The following illustration is for a remote thermostat, but the circuit can be
with a wide range of ICs:
The top and bottom isolators in the diagram could be combined into one IL712 rather
than two IL710s to reduce the chip count even more.
IL710 and IL712 Isolators are available in MSOP
packages to minimize board space.

NVE’s new top-of-the-line IsoLoop IL800-Series
isolated isolators will be featured by Hy-Line Power Components at
Vienna Tec, October 9 to 13 at Messe Wien
in Vienna, Austria.
Also in cooperation with Hy-Line Power Components, IsoLoop Isolators will be on
display at SPS IPC Drives, November 26 to 28 in Nuremberg, Germany. SPS
IPC Drives is billed as Europe’s leading exhibition for electric automation.
