Description
The IL600A-Series are isolated signal couplers with open-
drain outputs. They have a similar interface but better
performance and higher package density than optocouplers.
The devices are manufactured with NVE’s patented*
IsoLoop
®
spintronic Giant Magnetoresistive (GMR)
technology for small size, high speed, and low power.
A unique ceramic/polymer composite barrier provides
excellent isolation and virtually unlimited barrier life.
A resistor sets the input current; a capacitor in parallel with
the current-limit resistor provides improved dynamic
performance.
These versatile components simplify inventory requirements
by replacing a variety of optocouplers, functioning over a
wide range of data rates, edge speeds, and power supply
levels. The devices are available in MSOP, SOIC, and PDIP
packages, as well as bare die.

Failsafe Operation is defined as the guaranteed output state which will be achieved if the DC input current falls between the input levels specified
(see Test Circuit 1 for details). Note if Failsafe to Logic Low is required, the DC current supplied to the coil must be at least 8 mA using 3.3 V supplies
versus 5 mA for 5 V supplies.
