ELECTRICAL 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. High temperatures degrade operating lifetimes.

Operating lifetime is derated at temperatures greater than 105°C.

Note 2: All currents into device pins are positive; all currents out of device

pins are negative. All voltages are referenced to device ground unless

otherwise specified.

Note 3: Maximum data rate is guaranteed by other measured parameters

and is not tested directly.

Note 4: This IC includes overtemperature protection that is intended

to protect the device during momentary overload conditions.

Overtemperature protection actives at a junction temperature exceeding

150°C. Continuous operation above the specified maximum operating

junction temperature may result in device degradation or failure.
