Inverter Gates FAQ

What is the recommended bypass capacitor value for the VCC terminal?

A 0.1-µF capacitor is recommended for the VCC terminal to prevent power disturbances.

How should unused inputs be handled to ensure proper operation?

All unused inputs must be connected to either VCC or GND; they must never be left floating.
