Caution: Handling CMOS Devices
These devices contain circuitry to protect the inputs against damage due to high static
voltages. However, normal precautions should 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 crosstalk. 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.
