VCC = VL = 3.3V unless otherwise noted. (Note 2) 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. |
