Power Consumption

Signal Status on Start-up and Shut Down
Electrostatic Discharge Sensitivity
Isoloop devices achieve their low power consumption from
the manner by which 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 2.5ns wide, the power consumption is independent of
mark-to-space ratio and solely dependent on frequency. This
has obvious advantages over optocouplers whose power
consumption is heavily dependent on its on-state and
frequency.

It is recommended that low ESR ceramic capacitors be
used to decouple the supplies. 10nF capacitors should
be placed as close to the device as possible between V
and GND 1, as well as between V
To minimize power dissipation, the input signal to the
IL710 is differentiated and then latched on the output side
of the isolation barrier to reconstruct the signal. This could
result in an ambiguous output state depending on power up,
shutdown and power loss sequencing. Therefore, the
designer should consider the inclusion of an initialization
signal in his start-up circuit.
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.
