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