CD4013BE Unused Pins and outputs interference



Hi All,

I use CD4013BE for my design and I am having these questions, please help:

I use only half of the CD4013BE: 

Pin 1: Q

Pin 2: Q_bar

Pin 7 and Pin 14: GND and VDD +12VDC respectively

Pin 3: Clock

Pin 5: Data

Pin 4, Pin 6: Tied to GND

Should the IC's all other pins be tied to GND too?  The problem I have is intermittent.  I sometimes see the Output of Q and Q_bar on at the same time but they are not supposed to be.   Is that could be my timing between the CLK and DATA or no?

Thank you
