Handling Procedures
This device has built-in protection against high static
voltages or electric fields; however, anti-static precautions
must be taken as for any other CMOS component. Unless
otherwise specified, proper operation can only occur when
all terminal voltages are kept within the voltage range.
Unused inputs must always be tied to a defined logic
voltage level.
