The specifications for the 9264 do not include any information on glitch energy, nor is that a specification usually available. The information that is available that pertains to that is the settling time, which is defined below:
Settling time
20 V step.....................................20 μs
1 V step.......................................15 μs
0.1 V step....................................13 μs
I hope this is useful.
