Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
This Module includes overtemperature protection that is intended may cause permanent damage to the device. Exposure to any Absolute to protect the device during momentary overload conditions. Junction Maximum Rating condition for extended periods may affect device temperature will exceed 125°C when overtemperature protection is active. reliability and lifetime. Continuous operation above specified maximum operating junction
Note 2:
Guaranteed by design and not subject to production test. temperature may result in device degradation or failure.
Note 3:
Maximum Data rate is guaranteed by other measured parameters
Note 5:
Device considered a 2-terminal device. Pin group A1 through B8 and is not tested directly. 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.
