Table 3
Stresses above these listed maximum ratings may cause
permanent damages to the device.
Exposure beyond specified operating conditions may
affect device reliability or cause malfunction.
2.1
This device has built-in protection against high static
voltages
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.
