Note 1. Stresses beyond those listed under âAbsolute Maximum Ratingsâ 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 section of the

specifications is not implied. Exposure to absolute maximum rating conditions for extended

periods may affect device reliability.

Note 2. Input voltage measured with TOUT in highâimpedance state, VCC = 0V.
