NOTES: 1. Connecting any input terminal to voltages greater than V
*Static-sensitive device. Unused devices must be stored in conductive material. Protect devices from static discharge and static fields. Stresses above 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 above those indicated in the operation sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
