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: 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. Junction

temperature will exceed 150ºC when overtemperature protection is active.

Continuous operation above the specified maximum operating temperature

may result in device degradation or failure.

Note 5: Not tested in production.

swiTchinG characTerisTics The

denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VCC = 3.3V unless otherwise noted. (Note 2)
