UCC27524A: Question for ucc27524a input to output propagation delay specification

Part Number: UCC27524A Hi Experts, Our customer is curious about the input to output propagation delay specification for UCC27524A. In our datasheet, we stated that the min is 6ns, max is 23ns. If we look into the datasheet Figure 2, you will see we define the tD1 from input 90% High Level to output 10% High Level. So customer's questions are: 1. Can we explain it a little bit more details about the input to output propagation delay for this device? What's the major factor for this delay? 2. Is the tD1 equal to tD2 typically? In customer's real test, the tD1 is much longer than tD2, what's the influence in here? 3. What's the consideration for the tD1 and tD2 definition with input 90% High Level and output 10% High Level? As our understanding, it could be input 90% High Level and output 90% High Level.
