(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) When AVDD is turned off, TI recommends switching off the input clock (or ensure the voltage on CLKP, CLKM is <|0.3 V|). This prevents the ESD protection diodes at the clock input pins from turning on.

NOTE:

A high-going pulse on RESET pin is required in serial interface mode in case of initialization through hardware reset. If the pulse is greater than 1 µs, the device could enter the parallel configuration mode briefly then return back to serial interface mode. For parallel interface operation, RESET must be tied permanently HIGH.
