I am making a very simple half bridge DC motor drive using the MAX1760 gate driver. Looking through the datasheet I saw that it offers two types of logic level technologies (if that's the right word?); TTL and HNM. This may be a simple question, but why would someone want to use HNM over TTL? What trade offs do we make if we select HNM? Although I framed the question for DC motor application, I am interested in applications in broader sense too.
