Electrostatic Discharge Sensitivity
This product has been tested for electrostatic sensitivity to the limits stated in the specifications. However, NVE recommends that all integrated
circuits be handled with appropriate care to avoid damage. Damage caused by inappropriate handling or storage could range from performance
degradation to complete failure.
Narrow- and Wide-Body Pinout Differences
The narrow-body version (IL3585-3E) is designed for application flexibility and minimum board area in densely-populated PCAs. The wide-
body version (IL3585E) has redundant ground pins for layout flexibility.
The narrow-body version provides a separate isolated DE output (ISODE) and Transceiver Device Enable (XDE) input. ISODE follows the
Device Enable input (DE). XDE can be used to enable and disable the transceiver from the bus side, or connected to ISODE to enable and disable
the transceiver from the DE controller-side input. The narrow-body version also provides separate bus-side power supply pins—VDD2X for the
transceiver module and VDD2I for the isolation module. These pins should be externally connected for normal operation, but they can be used
separately for testing or troubleshooting.
The wide-body version has internal connections between the isolated DE output and the Transceiver Device Enable input, and well as between
the two VDD2 bus-side power supply pins. The two internally GND pins for each supply side provide layout flexibility. The ISODE output can be
used in PROFIBUS applications where the state of the isolated drive enable node needs to be monitored, or for testing or troubleshooting.
Dynamic Power Consumption
IsoLoop Isolators achieve their low power consumption from the way they transmit data across the isolation barrier. By detecting the edge
transitions of the input logic signal and converting these to narrow current pulses, a magnetic field is created around the GMR Wheatstone
bridge. Depending on the direction of the magnetic field, the bridge causes the output comparator to switch following the input logic signal.
Since the current pulses are narrow, about 2.5 ns, the power consumption is independent of mark-to-space ratio and solely dependent on
frequency. This has obvious advantages over optocouplers, which have power consumption heavily dependent on frequency and time.

Power Supply Decoupling
Both VDD1 and VDD2 must be bypassed with 47 nF ceramic capacitors. These should be placed as close as possible to VDD pins for proper
operation. Additionally, VDD2 should be bypassed with a 10 F tantalum capacitor.
Maintaining Creepage
Creepage distances are often critical in isolated circuits. In addition to meeting JEDEC standards, NVE isolator packages have unique creepage
specifications. Standard pad libraries often extend under the package, compromising creepage and clearance. Similarly, ground planes, if used,
should be spaced to avoid compromising clearance. Package drawings and recommended pad layouts are included in this datasheet.
DC Correctness
The IL3585 incorporates a patented refresh circuit to maintain the correct output state with respect to data input. At power up, the bus outputs
will follow the Function Table shown on Page 1. The DE input should be held low during power-up to eliminate false drive data pulses from the
bus. An external power supply monitor to minimize glitches caused by slow power-up and power-down transients is not required.
