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.
