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 Module 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 5: Device considered a 2-terminal device. Pin group A1 through B8

shorted together and pin group K1 through L8 shorted together.

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

a continuous voltage rating.
