Handling Procedures
This device has built-in protection against high static
voltages or electric fields; however, anti-static
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.
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.

Note1:
The current consumption when the output clock is enabled (OE pin at V
DD
) is a function of the load capacitance on
the OUT pin, the output frequency f
OUT
= 32768Hz and the supply voltage V
DD
.
The additional consumption for a given load can be calculated from:
