† 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 under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

‡ Electrical characteristics are specified with all output buffers loaded with the specified IO current. Exceeding the specified IO current in any buffer

can affect the levels on other buffers.

NOTE 1: Unless otherwise noted, all voltage values are with respect to VSS.
