NOTE 1: Input voltage measured with TOUT in high-impedance state, SHDN or VCC=0V  
NOTE 2: For the MAX220, V+ and V- can have a maximum magnitude of 7V, but their absolute difference cannot  
exceed 13V.  
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These  
are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in  
the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for  
extended periods may affect device reliability
