Stresses above these listed maximum ratings may cause
permanent damage 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 due to the unique properties of this
device, anti-static precautions should be taken as for any other
CMOS component.
