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,
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.
