ISOLATION CHARACTERISTICS

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 test.

Note 3: This µModule transceiver includes overtemperature protection that

is intended to protect the device during momentary overload conditions.

Junction temperature will exceed 125°C when overtemperature protection

is active. Continuous operation above specified maximum operating

junction temperature may result in device degradation or failure.

Note 4: Maximum data rate is guaranteed by other measured parameters

and is not directly tested.

Note 5: Device considered a 2-terminal device. Measurement between

groups of pins A1 through B6 shorted together and pins W1 through X6

shorted together.

Note 6: The rated dielectric insulation voltage should not be interpreted as

a continuous voltage rating.

Note 7: In accordance with UL1577, each device is proof tested at the

7500VRMS rating by applying an acceleration factor of 1.2, 9000VRMS, for

one second.

Note 8: Evaluated by design, not production tested.

Note 9: Ratings are for pollution degree 2, material group 3 and

overvoltage category II where applicable. Ratings for other environmental

and electrical conditions to be determined from the appropriate safety

standard.
