† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The package thermal impedance is calculated in accordance with JESD 51-7.

NOTE 2: To ensure proper device operation, all unused inputs must be terminated as follows: A and control inputs to VCC(5 V) or GND, and
B inputs to GND only. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
