NOTES:  
2. Connecting any input terminal to voltages greater than V+ or less than GND may cause destructive latchup. It is recommended that no inputs  
from sources operating from external supplies be applied prior to “power up” of the ICL7660, ICL7660A.  
3. Derate linearly above 50°C by 5.5mW/°C.  
4. In the test circuit, there is no external capacitor applied to pin 7. However, when the device is plugged into a test socket, there is usually a very  
small but finite stray capacitance present, of the order of 5pF.  
5. The Intersil ICL7660A can operate without an external diode over the full temperature and voltage range. This device will function in existing  
designs which incorporate an external diode with no degradation in overall circuit performance.
