Table 21. Maximum Ratings
Note: Exceeding the absolute maximum rating may damage the device. Stresses greater than those listed in the table above may cause permanent
damage to the device. Operation of the device at these or any other conditions above those specified in the operating sections of this specification is not
implied. Maximum conditions for extended periods may affect reliability. Unused inputs must always be tied to an appropriate logic voltage level.
