Handling CMOS Devices
The device contains 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 to + (VGG + 0.5V). This
prevents forward biasing the input protection diodes and possibly entering a latch up
mode due to high current transients.
