(1) All unused inputs of the device must be held at V_CC or GND for proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004.

(2) Recommended current values provided to maintain appropriate output state as per the relevant output voltage specification (V_OL for I_OL, V_OH for I_OH). See Electrical Characteristics table for details.
