† 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.

NOTE 3: All voltage values are with respect to VSS.

‡ This IOH can be exceeded when using a 1-kΩ pulldown resistor on the TDM serial port TADD output; however, this output still meets VOH

specifications under these conditions.
