Hi Pablo,

Customer need min/max values for worst case calculation. Please provide any estimated values based on simulation or calculation if there is no test data available. Thank you.

Hi PY,

Thanks for the information.

We should have these values in our database. However, I don't have access to our TI network at the moment so I can't access the data. Please give me until Monday to provide you with the values.

Hi PY,

The min and max values are 118ns and 330ns respectively. These values were measured during characterization of this device but TI does not guarantee that these values will always be correct. The only specifications which are guaranteed, under the given test conditions, are the ones which are given in the datasheet.
