Handling Procedures
This device has built-in protection against high static
voltages or electric fields; however, anti-static precau-
tions should be taken as for any other CMOS compo-
nent. Unless otherwise specified, proper operation can
only occur when all terminal voltages are kept within
the supply voltage range.
