Stresses above these listed maximum ratings may cause
permanent damage to the device. Exposure beyond
specified operating conditions may affect device
reliability or cause malfunction.
Handling Procedures
This device has built-in protection against high static
voltages or electric fields; however, it is advised that
normal precautions be taken as for any other CMOS
component.
Unless
otherwise
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.
