(1) If this device is used in the threshold region (from VILmax = 0.5V to VIHmin = 1.5V), there is a potential to go into the wrong state from induced grounding, causing double clocking. Operating with the inputs at tt = 1000ns and VCC = 2V does not damage the device; however, functionally, the CLK inputs are not ensured while in the shift, count, or toggle operating modes.
(2) All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
