For standard logic ICs, although it states that it is appropriate to connect unused input terminals to the power supply or ground, is it necessary to connect a resistor in series?
- Although resistance is not strictly necessary for pull-up or pull-down, since the input pin has a high impedance, it may be affected by external noise when connecting a resistor on the order of MΩ.
