Sindhu,
I see that you have not received an answer to your question. Be aware that comparators are fabricated on many different IC processes and supported by several different product groups in TI. Your question is far to broad to allow a simple answer. If you have a question on a specific comparator (part number) you may have greater success getting an answer. Still, this is the type of information that the supporting product group may not be willing to share.
Best place to ask this question is on the "etc... Amps Forum," not this forum.
