1) Rise/Fall time parameters are taken with 10% - 90% of supply.
2) Not all parameters are 100% tested, but are verified by design/characterisation and test correlation.
3) Additional rise/fall time valid for CL = 20 pF - CL = 100 pF @ 0.125 ns/pF at 5 V supply voltage.
4) Additional rise/fall time valid for CL = 20 pF - CL = 100 pF.@ 0.225 ns/pF at 3.3 V supply voltage.
