Hi,
I've got a circuit that uses 2 of the 6 inverters on a CMOS 4069 chip. I had read that it was a bad idea to leave unused pins floating, so without doing much research, I decided to tie all of the unused input and output pins to ground....and this doesn't seem to have been a very good idea. I did notice that I was pulling around double the expected current through the circuit with this arrangement...and then found that the IC had been totalled
So, question is, which pins should I tie? Now that I've given it a bit more thought, I am thinking of just grounding all of the unused input pins, and leaving the outputs floating.
Is this a reasonable solution?
