I have been characterizing the Intersil IS82C55AZ and have found it to be both faster and stronger than reported in the data sheet.

No! Read again the datasheet very carefully and you will see that the chip exactly does what the datasheet tells!

The 8255A is stronger and faster than reported.            01/01/70 00:00      
   The Data Sheet rules            01/01/70 00:00      
      How can we rely on that specification?            01/01/70 00:00      
   Not proven!            01/01/70 00:00      
   who give s hoot what you have 'found'            01/01/70 00:00      
      Data sheets don' rule in reverse engineering            01/01/70 00:00      
         Does that mean...            01/01/70 00:00      
            I'm a chip provider, not a user            01/01/70 00:00      
               then do notstate "The 8255A is stronger and fast"            01/01/70 00:00      
                  8255 statements            01/01/70 00:00      
         They do determine what you have to deliver ...            01/01/70 00:00

               Hmmmm ...            01/01/70 00:00

                     What did you really test?            01/01/70 00:00      
                        DC measurements            01/01/70 00:00      
                           That's why measurements are quick and automatic            01/01/70 00:00
