Note
:
2. All unused inputs of the device must be held at Vcc or GND to ensure proper device operation.
3. If this device is used in the threshold region (from V
IL
max = 0.5 V to V
IH
min = 1.5 V), there is a
potential to go into the wrong state from induced grounding, causing double clocking. Operating
with the inputs at t
t
= 1000 ns and Vcc = 2 V does not damage the device; however, functionally, the
CLK inputs are not ensured while in the shift, count, or toggle operating modes.
