switching Characteristics The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. LTM2882-3 VCC = 3.3V, LTM2882-5 VCC = 5.0V, VL = VCC, and GND =
GND2 = 0V, ON = VL unless otherwise noted.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Guaranteed by design and not subject to production test.
Note 3: Maximum Data Rate is guaranteed by other measured parameters
and is not tested directly.
Note 4: This device includes over-temperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 105°C when overtemperature protection is active.
Continuous operation above specified maximum operating junction
temperature may result in device degradation or failure.
Note 5: Tests performed from GND to GND2, all pins shorted each side of
isolation barrier.
Note 6: The rated dielectric insulation voltage should not be interpreted as
a continuous voltage rating.
