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.
