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.
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.

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