Hi All,
I know that you have to tie unused CMOS input pins to GND or VCC to prevent the circuitry from switching due to static charge due to drawing extra power I am guessing? Do you make these connections as direct connections, or should there be a current limiting resistor in the mix?
As a parallel question, what about unused CMOS outputs? For example I have a 4 channel AND gate chip that I am only using 3 channels on. I'm assuming this output pin should be left unconnected (floating) since a connection to VCC or GND could damage the chip. Is this correct?
Thanks!
