Therefore, try as much as possible to apply the voltage level close to VDD or GND. (4) Handling of unused pins Since the input impedance of the input pins is extremely high, operating the device with these pins in the open circuit state can lead to unstable voltage level and malfunctions due to noise. Therefore, pull- up or pull-down resistors should be provided for all unused input pins. 12-2. Notes on packaging (1) Soldering heat resistance. If the temperature within the package exceeds 260, t
