ABSOLUTE MAXIMUM RATINGS* (Voltages referenced to V  
SS(A)  
and V  
)
SS(D)  
This device contains protection circuitry to  
guard against damage due to high static volt-  
ages or electric fields. However, precautions  
must be taken to avoid applications of any volt-  
age higher than maximum rated voltages to  
this high–impedance circuit.
