Hello,
I'm currently working on my Final Year Project for university and have read that to ensure stable operation all unused logic inputs should be tied to either +V or 0V when using CMOS.
There however doesn't seem to be clarification as to whether this means unused inputs on a currently in use function on not. What I mean by this is, for example, a 4013 dual D type flip flop... if I am using only one of them, should I tye all the inputs of the other to 0V or does it just mean tying set and reset for example on the flip flop I'm using?
I have scoured all over the net and in many reference books but not found a clear answer. My technician at university says it only applies to the flip-flop or logic gate in use and not other functions in the same IC.
Any clarification would be appreciated and if anyone has a reference source too that would be fab, but don't worry if not!
Also another quick question, does CMOS stand for Complimentary Metal Oxide Semiconductor or Silicon? I have read both in different texts, although I thought it was semiconductor initially?
