† 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.
