Caution: Handling CMOS Devices
These devices contain circuitry to protect the inputs against damage due to high static voltages. However, it is advised that
normal precautions be taken to avoid application of any voltage higher than maximum rated voltage.
An unterminated input can acquire unpredictable voltages through coupling with stray capacitance and internal cross talk.
Both power dissipation and device noise immunity degrades. Therefore, all inputs should be connected to an appropriate
supply voltage.
Input signals should never exceed the voltage range from 0.5V or more negative than GND to 0.5V or more positive than
VDD. This prevents forward biasing the input protection diodes and possibly entering a latch up mode due to high current
transients.
