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 specied.

The ● denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C, VCC = 3.3V, TE = 0V unless otherwise noted (Note 2).
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 activates at a junction temperature exceeding
150°C. Continuous operation above the specied maximum operating
junction temperature may result in device degradation or failure.
The ● denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C, VCC = 3.3V, TE = 0V unless otherwise noted (Note 2).
